how to identify native conifers UK

Which Conifer Trees Are Native to Britain?

Are you confused by conifers and flummoxed by firs? In this article you’re going to get to know the native conifer trees of Britain & Ireland and learn the top five key features you need to look for so that you can easily recognise them in the countryside and tell them apart from the many non-native conifers you may find.

Conifers are not rare in this country, you can find them everywhere. As a general rule, they are also evergreen (though there is an exception, the Larch) so they hang on to their foliage right through our winter. With the majority of our native trees being broadleaves, losing their leaves in autumn, this makes a conifer easy to spot from a mile off.

But are you looking at one of our native conifer trees or is it one of the many non-native species which have been introduced to this country?

I am hosting an online workshop How To Identify Conifers where I will break down the key features of both our native and common non-native conifers. So, if you are perplexed by pines or stumped by spruce then you should join me for that.

 

What is a Conifer?

Conifers are a very old group of trees that includes firs, cedars, cypresses, junipers, kauri, larches, pines, hemlocks, redwoods, spruces and yews. As a rule, conifers bare cones, though some don’t look much like cones as we think of them. The other key feature they share is they have very small leaves in the form of needles or scales.

With the exception of some Scots Pine in Scotland and a few Yew woodlands, you will not comes across a natural forest of conifer trees in the UK and Ireland. They are most likely planted non-native species, usually for timber production or as a shelter-belt woodland.

When we picture a conifer, we usually have a Christmas tree in mind, which is typically a Spruce. But there’s more to conifers than simply this conical cone-baring form. Especially when it comes to our own natives.

how to identify conifers

Above: Conifers can come in a variety of weird and wonderful forms.

 

How Many Native Conifers Do We Have in the UK & Ireland?

Well the good news here is that we have only three native conifers. By native, we mean a species which have been naturally present on these isles since the last Ice Age and before we became disconnected from the continent. Our three native conifers are Scots Pine, Juniper and Yew.

Take a trip around the globe and you could be dealing with up to 800 conifer species. So, we’re quite lucky in the UK & Ireland that we only have three to tackle.

It’s not just the trees featured in this article that you could well see on your country walk though. There are several species and families of conifer trees that are very commonly planted here, either for forestry or in country estates and parks for their sheer beauty. You’d be forgiven for thinking that Larch, Spruce, Firs and Hemlock could be part of the natural make of our landscape but they are all guests from exotic lands.

So, let’s get to know our three natives and pick out the key identifying features you need to look for.

 

Scots Pine (Pinus sylvestris)

There are several pines which has been introduced to this country including the Corsican Pine (Pinus nigra var. maritima) and Lodgepole Pine (Pinus contora ssp. latifolia) to name a couple, but we have only one native and the clue is in the name, Scots Pine. However, don’t be fooled, this tree isn’t found only in Scotland, you could see it anywhere. In its natural range though it does favour uplands and poor soils. The oldest Scots Pine in the UK can be found in Scotland in the Caledonian Forest.

how to identify scots pine - pinus sylvestris

Left: Needles are in pairs, joined at their base. Middle: A ripe cone, still closed. Right: A mature cone having dropped its seeds.

Before we get into the specific details of Scots Pine, it’s worth mentioning a feature that is unique to pines. If you follow a single pine needle back to its base, where it joins the twig, you will discover it is joined to one or more other needles. Pine needles come in twos, threes or fives. This is important because conifers like spruce have needles which are attached singly to the twig.

I was told this handy little rhyme by Dave Watson of Woodland Survival Crafts to help me remember this rule; “If it’s a pair, it’s a pine, but not all pines are pairs.” By using this rhyme we can eliminate other families of conifers and know that we are looking at a pine. So, that leads to the question, how do we know it’s a Scots Pine?

To identify the Scots Pine there’s a few key features to look for:

  1. Needles come in pairs, joined at their base to the twig. Needles are approx 5 to 7.5cm in length. This is important as a commonly planted non-native, the Corsican Pine, also has needles in pairs, but they are significantly longer. Corsican Pine needles can grow to 15cm long.
  2. Needles often have a twist to them.
  3. Mature bark is a warm brown to orange colour with a craggy character. Also, look for a band of orange on the main trunk about a third to two-thirds up the tree. This is especially visible in clear sunlight.
  4. Pine cones. These are the typical cones used for Christmas decorations that you are probably familiar with. They take two years to mature. Cones are green and conical in their first year on the branch. In their second year they become more rounded and brown-grey in colour.
  5. Mature trees have a habit of spreading  and flattening out in their crown, so losing the “Christmas tree” conical shape we think of when picturing a conifer.

 

 

how to identify scots pine - pinus sylvestris

Left: Look for an orange band on the trunk some way up the tree. Middle: Bark is craggy and covered in plates. Right: The crown of mature trees flatten out.

 

Juniper (Juniperus communis)

You might know this tree best from its berries, or rather what’s its berries are used to flavour… gin.

This is by far the least common of our three native conifers. It is mostly a tree of upland areas, but you can find it formally planted in country estate gardens where it can be trimmed to shape. It’s worth noting though that Juniper is probably the most widespread tree species in the world, found from the Arctic to the Mediterranean.

how to identify juniper - juniperus communis

Left: Typically a low-growing and spreading tree. Middle: Ripe berries are blue to black in colour. Right: Needles grow in threes. They are very spiky.

In the UK, Juniper tends to favour chalk and limestone sites.

To identify Juniper you’re looking for the following things:

  1. Typically a low-growing, sprawling shrub of a tree. Though not always.
  2. Needles are small (up to 2cm long), very spiky to touch and they grow in threes.
  3. The mature bark is a reddish-brown colour which has a peeling habit.
  4. Berries. When mature they are dark blue/black. They are small and spherical. When young they are green in colour. You will only find them on the female trees. So, this feature can be a little unreliable.
  5. Crush a berry between you fingers, it will smell of gin. This also works with the twigs & foliage, but be careful, it’s spiky!

The ripe fruit of the female Juniper are generally called berries, but they are actually classed as cones.

There are several cultivated varieties of Juniper which you can pick up in your local garden centre.

how to identify juniper - juniperus communis

Left: Bark is reddish-brown and peeling. Middle: Young berries are blue/green. Right: Juniper can be an upright, single-trunked tree, but this is less common.

 

Yew (Taxus baccata)

We can lay claim to some of the most spectacular Yew trees in the world, as they are the oldest living organisms in the UK. It’s thought that some are as old as five thousand years! There is hot debate as to which is the oldest living Yew, but the most likely candidates, in my opinion, are in Wales.

how to identify yew - taxus baccata

Left: Yews are often found in churchayrds. Middle: Needles are soft to touch. Right: Bark is patchy with reds, browns & purples.

You are most likely to find a Yew in your local churchyard, looming over the gravestones. Many of these trees predate the church they are paired with.

To identify the Yew tree you’re looking for a few key things:

  1. Glossy needles are up to 4cm long. They are arranged flat, along green twigs.
  2. The needles are soft to the touch, unlike spikier spruce trees.
  3. The mature bark of Yew is quite beautiful. Look for red-brown bark with a peeling habit that can show patches of oranges, purples and blood red. When wet, patches of the bark can look like they’re bleeding.
  4. The bright pink/red oval berries of the Yew are very different from anything else you’ll find on a conifer. You will only find these on female trees, so don’t rely on this alone.
  5. Mature trees will typically have more than one stem, growing from the base.

Yew trees don’t have cones. This makes them easy to distinguish from pine, spruce and fir.

free winter tree id guide to UK & Ireland

FREE Winter Tree ID Guide

Many of us might well be able to spot an oak in winter by looking for fallen acorns or the familiar leaves, but could you tell me the difference between blackthorn and hawthorn in winter just by looking at the buds? Or do you know which trees give themselves away in winter by their bark? We might be able to identify trees in summer when their leaves are on but winter is a whole different ball game.

For anyone looking to improve their tree identification skills winter provides us with many distinctive signs such as buds, bark, twigs and fallen leaf litter that we can use to recognise our native and common tree species. The clues are all there if you know how to look.

In this blog I’ll introduce you to some of clues to look out for in winter and break down the differences between common trees which often get confused. You can get outdoors and spot these clues for yourself with a free download I’ve created; Winter Trees Guide, which you can get your hands on just below.

free winter tree id guide to download

By the way, if you love trees, but struggle to tell one species from another, then you could enrol in my FREE Tree Identification Course online. More details can be found at the end of the article.

 

Bud Arrangement: The BIG Giveaway

One of the first things you can ask a tree when you are trying to identify it in winter is this; “Are the buds arranged alternately or in opposite pairs?”

This is absolutely key to nailing the species of tree as once you’ve answered that question it allows you to eliminate a whole bunch of species from your enquiry.

The majority of native tree species in Britain have their buds arranged alternately along the branch.

One last thing to remember; it’s important to select a young healthy twig to answer this question because as a branch matures it will often self-select the healthiest of the twigs to grow on and will drop it’s near partner. So, you can be looking at an older branch and thinking that they definitely don’t grow in opposite pairs, but then on closer inspection you might well notice the old scar left over from where it’s opposite equivalent was self-selected to be dropped by the tree in favour of it’s partner.

When you become practised at this you will begin to start noticing the bud arrangement from a distance, as you look at the form of tree. This is when tree identification can become very satisfying and you can really start showing off.

In the Free Winter Tree ID Guide I’ve grouped alternate budding trees separate from opposite budding trees for easy reference.

 

Blackthorn vs. Hawthorn

Let’s take two very common trees which often get confused. Not only are their names similar, but they also are thorny, shrubby trees which populate our hedgerows, often growing side by side.

To help confuse matters both these species have alternate buds and the buds are very small and grow in cluster at the end of the twig. So, we need to look at other clues to help us out.

hawthorn and blackthorn winter tree identification

Above: Blackthorn (Prunus spinosa) on the left, Hawthorn (Crataegus monogyna) on the right. The difference is clear.

The first thing to look for is leaf litter below the tree. As you can see from the picture, the leaves shapes are very different. However, this method is unreliable when you’re looking at a dense hedgerow and the two species are intertwined. How can you tell which tree the leaf has fallen from? Luckily, there are other signs we can go to also.

identifying blackthorn and hawthorn in winter

Above: Blackthorn on the left, Hawthorn on the right. Bark is a feature you can use year round to identify a tree.

Looking at the bark is going to be useful here as, like the leaf litter, they are very different. The bark of blackthorn, as its name suggests, is very dark and seems to soak up the light. It is also generally quite smooth. The bark of hawthorn is much more grey to brown and fissures readily, being much more craggy.

As well as the bark you can look at the thorns, which typically you will see a lot more of on blackthorn than you will compared to hawthorn. The last sign to help us here is the autumn fruits, which can often be found still hanging on in winter.

comparing blackthorn and hawthorn in winter

Above: On the left, Blackthorn can hang on to a few withered & dried sloes in winter. On the right, hawthorns often has smaller, deep red berries on show in winter.

The autumn fruit of blackthorn is the sloe. A good size fruit, around 1.5cm diameter and purple to black in colour. In winter though they are shrivelled and looking much worse for wear, with most of them having fallen already. Hawthorn in comparison holds onto it’s berries better in winter. Look for smaller, dark red berries, with an ovoid shape, growing in sparse clusters. As they dry out they darken in colour.

 

Looking Under The Tree

Have a good kick about in the leaf litter under a tree and you might find another big hint to what species you’re looking at. The old saying goes “the apple never falls far from the tree” and that’s good news for us in this case. I’m talking about fallen fruits and nut cases, many of which can still be found in the depths of winter, if not in the best condition.

winter tree identification: fallen fruits and nuts

Top Left: Crab Apples. Mid Top: Sweet Chestnut. Top Right: Hazelnuts, nibbled by wildlife. Bottom Left: Conkers from Horse Chestnut. Mid Bottom: Beech mast and leaf litter. Bottom Right: A bract from a Lime tree.

Some trees, like the Crab Apple, have a dead giveaway with the fallen, rotting fruits. Look under an established hazelnut and you’ll most likely find empty nut shells, nibbled away by rodents and birds. Then there’s tree like out three native Limes which have special leaves called bracts, which look like nothing else you’ll find on the woodland floor and can only belong to a Lime tree. Beech mast is very reliable under mature trees and you’ll find yourself crunching in underfoot as it carpets the woodland floor. There’s much to be gained by looking down.

Now this only works if there’s something to find and also you should be wary of relying on this too heavily where the tree is crowded with others as  what you’re looking at may have fallen from it’s neighbour.

By the far the most reliable method of winter tree identification is to begin with a branch and study a healthy twig and it’s buds. That way we can be sure we’re investigating the right tree and the knowledge of bud and twig is transferable no matter whether the ground below is humous or concrete.

 

Get Your FREE Winter Tree Guide

I’ve created a handy guide you can use when you’re out and about looking at trees during winter. The guide features 18 native and common British trees which have buds, twigs and leaf litter that you might already be familiar with but also there’s other signs here that you’ve probably never noticed before. I’ve laid out similar looking species side by side so that you can easily distinguish between them.

The guide puts the focus firmly on the winter buds but you’ll also see smaller images featuring other clues you can look for in each species such as old fruits, leaf litter, nut cases, bark and catkins. Where I’ve included these they act as dead giveaways to which tree species you’re looking at.

I hope you find it useful on your journey to understanding the trees around us.

3 Common Maple Trees

Maple leaves are quite a distinctive shape, just think of the Canadian flag. But we have several maple species commonly growing in our countryside and when it comes to including formal planting and gardens that numbers goes sky high. We shall steer clear of those for now. Let’s just look at the differences between our 3 most common maple trees which you’re most likely to see on a country walk. We will look at the difference in their leaves in autumn and also their fruits.

comparing autumn maple leaves

Left: Field Maple (Acer campestre), Middle: Sycamore (Acer pseudoplatanus), Right: Norway Maple (Acer platanoides)

So, we have 3 different maples each with their characteristic 5-lobed leaf shape. But they are also clearly quite different, especially as autumn reveals it’s colours. Let’s break that down…

Field Maple (Acer campestre) – our only native maple in the UK. Firstly, the leaves are much smaller than the other two species here and the tree itself is smaller when mature also. The lobes are more rounded than the others. But a key difference to look out for is the leaf colour in autumn, which across the whole tree will be a bright yellow. The best example is the leaf seen in the extreme left. Once they fall, they will turn brown.

Sycamore (Acer pseudoplatanus) – a commonly planted non-native maple. We’ve got a much larger leaf here than the field maple, but also the presence of Tar Spot Fungus – have you noticed those black spots? You don’t get these spots on our other two maples here, so it’s a dead giveaway. There’s something interesting about the autumn leaf colour too, in that there isn’t much to shout about. Typically you won’t see a great display of colour from our sycamores, they generally just turn a dirty/patchy brown. This is in contrast to our other two species here. Take caution though; sometimes we do get yellow leaves across the tree, but this is less common. Natures loves not conforming to simple rules 🙂

Norway Maple (Acer platanoides) – next to sycamore this is probably the most commonly planted non-native maple in the UK, particularly in urban areas and roadsides. We have a larger leaf, like sycamore, but the lobes are much more jagged and dramatic in their form. We also can’t ignore the amazing display of colours we get from norway maple, which is a world away from sycamore at this time of year. Just look at those reds, oranges and yellows.

In summer, all these leaves are green, of course. But come the autumn you can clearly see the differences. Let’s not forget the fruits of the maples either, what many people call “helicopters.” These winged seed cases are a favourite of children who love throwing them in the air and watching them spin to the earth. Let’s take a look at the differences between our 3 maples when it comes to these “helicopters.”

comparing maple seeds

Left: Field Maple (Acer campestre), Middle: Sycamore (Acer pseudoplatanus), Right: Norway Maple (Acer platanoides), Inset: Sycamore seeds in autumn

You can see the clear difference in not only the typical size of the winged seeds but also their shape. Field maple seeds typically have their wings at 180 degrees to each other, whereas sycamore wings are generally at a more down-swept 45 degrees. The norway maple wings are larger again. By the way, this picture is of the seeds in summer, when they are not fully mature so be aware that in autumn the mature wings will all be brown in colour, as seen in the inset picture.

I hope that’s cleared up any confusion between these 3 common maples. Now, let’s look at some autumn berries which can be the cause of confusion.

 

Red Berries Everywhere

To someone starting out in tree identification, it can be easy to get confused between tree species which have similar berries, especially when they’re the same colour. Just take a look at these below…

uk native trees in autumn: red berries

Top Left: Hawthorn (Crataegus monogyna), Top Right: Guelder-rose (Viburnum opulus), Bottom Left: Rowan (Sorbus aucuparia), Bottom Right: Whitebeam (Sorbus aria)

Here we have four different native trees, each with red berries. So, how can we easily tell between them? Well although this may seem confusing at first glance there are differences to see once we slow down and look closer. Here’s my handy hints for telling these trees apart in autumn:

Hawthorn (Crataegus monogyna) – this is the 3rd display of colour we’ve had from this tree over the year. The first being the flush of spring green leaves which fill our hedgerows and roadsides. The second comes in May with the white blossom, smelling of sweet almonds. This third display are the berries themselves, known as haws. They are round to oval in shape, with a matt finish. Inside you’ll find the flesh is a yellow/green colour which surrounds a large stone. You will see less fruits per bunch than you will with the other species here. Also, look out for the thorns on the branch, which these other species don’t have.

Guelder-rose (Viburnum opulus) – a common shrub of hedgerows. Firstly these striking red berries grow in umbels (a cluster of stalks), unlike the hawthorn. Also, these berries are really glossy. They have a real shine to them. The flesh inside is red, with the whole berry being much less firm than the others here. Lastly, their shape is important, which is more difficult to see from the above picture, but they are partially flattened, as if their round shape has been squashed.

Rowan (Sorbus aucuparia) – you may know this tree as the mountain ash. These berries grow from an umbel, with many berries per cluster. The seed inside is much smaller than that of hawthorn. The month you’re seeing these berries is also important too because they can appear on the tree as early as July and can persist after the leaves have fallen in autumn. So, they have a long season on the branch. Beware that there are many cultivars of rowan which are planted in urban spaces. You can even get orange or yellow berry varieties. But in the countryside, you’re unlikely to see these.

Whitebeam (Sorbus aria) – These are the largest berry of the four seen here. A feature which is difficult t pick up from this image is that the berries are peppered with white/grey spots called lenticels. Notice the latin family name ‘Sorbus’, this species is related to our rowan. So, it’s no surprise there are some similarities in how the berries look. Like the rowan, there are several cultivars of whitebeam which you might well see in urban areas and gardens, so we’re just talking about the wild native here.

 

We’re missing a key piece of the puzzle here though, the leaves. We need to widen our view of these trees because if we just look at the berries we’re not using all of the information available to us. Take a look at the images below and you’ll see that we have four very different leaf shapes with their respective autumn colours.

autumn leaf collage

Top Left: Hawthorn (Crataegus monogyna), Top Right: Guelder-rose (Viburnum opulus), Bottom Left: Rowan (Sorbus aucuparia), Bottom Right: Whitebeam (Sorbus aria)

So, as we can now see, with the full picture things become a little easier. This is one of the big things I ask my students to practise when they’re out identifying trees. I ask them to “Tune In” so they look at the bigger picture before concentrating on the details. Clues like leaf shape, bark, or even the place where the tree is growing can tell us a lot about what we’re looking at.

FREE Spring Tree Flower Guide

Ask someone “what grows on oak trees” and most people will say “acorns” but have you ever noticed the beautiful pink flowers growing on oak? There’s a hidden world of wonderful tree flowers that many of us walk right by without giving them a glance. In this blog I’ll introduce you to some of the best tree flowers to look out for in spring. You can find them yourself with a free download I’ve created Spring Trees: Flower Guide UK, which you can get your hands on just below.

Which Trees Have Flowers?

The simple answer to this is that all our native and common broadleaf trees have flowers. When you get to conifers (evergreens) things get a little more tricky so let’s set those aside for now.

Most of our trees show their flowers in spring but some, like the elder, wait until early summer. Knowing what order the flowers emerge in spring can be a good skill to help you identify which tree species you’re looking at. Male flowers will become laden with yellow pollen whilst the (usually) more colourful female flowers will eventually mature into the seed, fruit, nut or berry.

The majority of our trees have both their male and female flowers on the same branch, sometimes right next to each other, but others have separate male and female trees, relying on their being a member of the opposite sex in the near vicinity for pollination to occur. I wrote a whole article about which trees are male and female, if you want to know more just follow this link.

Trees like willow and poplar don’t have flowers as we usually know them, with petals, but rather they have catkins, which fill the early spring canopy with whites and yellows. As spring comes to a close the female catkins have gone to seed and you can have sunny May days with masses of fluffy willow and poplar seeds gently floating through the breeze. If you want to find out more about catkins, I’ve written a whole article about them. You can check that out here.

 

3 Tiny, But Beautiful Tree Flowers To Look Out For

3 amazing but tiny tree flowers

3 Beautiful Native Tree Flowers To Hunt Down; English Oak (Quercus robur), Hornbeam (Carpinus betulus) and Alder (Alnus glutinosa).

They may be small but that doesn’t mean these tree flowers don’t pack a visual punch when you do spot them. Earlier in the season (late winter) we have the tiny flowers of the hazel (Corylus avellana) looking like red tentacled sea-anemones. They are one of the first signs that spring is on its way.

But there’s three more crimson beauties I want to draw your attention to. First we have the female flowers of our native oaks. The green male catkins are also found growing on the same branch. You will find these tiny pink flowers appearing with the young leaves in late April to early May. Look out for them as they won’t be there for long.

Hornbeam, often mistaken for beech (Fagus sylvatica), is another native which produces two very different male and female flowers, the males being catkins. The females resemble the flowers of hazel, with pink tendrils spread out to catch pollen. You will find these on the tree in April.

Lastly, the alder, a tree which favours wet ground and riverbanks. It has not only vividly purple buds and male catkins, but in early spring you might well spot the young female flowers before they turn green and begin their journey to maturing into cones. When young they resemble bright pink cotton buds, a real splash of colour in February and March. Keep your eyes peeled!

 

Know Your Tree Flowers

To someone starting out in tree identification, it can be easy to get confused between tree species which have similar flowers, especially when they’re the same colour. Just take a look at these below…

how to identify spring tree flowers

Top Left: Blackthorn (Prunus spinosa), Top Right: Crab Apple (Malus sylvestris), Bottom Left: Wild Cherry (Prunus avium), Bottom Right: Hawthorn (Crataegus monogyna)

Here we have four different native trees, each with white flowers, with 5 petals each. So how can we easily tell between them? Well although this may seem confusing at first glance and each of these species could be found growing next door to one another, what we don’t have here is context. What I mean here is specifically the time of year we would find these flowers. The other thing we need to consider is other identifying signs away from the flowers themselves. Here’s my handy hints for telling these trees apart in spring:

Blackthorn (Prunus spinosa) – this is the first tree to come into flower en masse in our hedgerows. We see this in March when everything else still has closed buds.  Also, look out for the wicked thorns on the twig and trunk.

Crab Apple (Malus sylvestris) – this is the largest of the four flowers shown here. Notice how the petals are really opened out. They resemble an apple core when it’s sliced crossways, looking like a 5 pointed star. These flowers are typically out in May. Also, you will probably find rotten apples on the ground below the tree, so look out for those.

Wild Cherry (Prunus avium) – these flowers can closely resemble the hawthorn, however the flowers of wild cherry emerge before the leaves in April whereas with hawthorn the flowers come out after the leaves. Also, you will not find any thorns on a wild cherry.

Hawthorn (Crataegus monogyna) – one of the key features for these flowers is their smell. The have a sickly-sweet (though I think it’s pleasant) aroma of almond or marzipan. You will find these flower in late-April to May. An old country name for this tree is the maythorn because it traditionally flowers at this time of the year. Remember, the tree has thorns, so look for those too.

trees versus shrubs what's the difference

Is It A Tree Or A Shrub?

Have you ever wondered what the difference is between a tree and a shrub? The answer does not always seem clear. Is an ancient oak, growing small and stunted on a mountainside classed as a shrub or a tree? In this article you’re going to learn the difference between trees and shrubs. It’s a question that many of the students on my FREE Tree Identification Course have asked me, so I thought I’d tackle it here.

When we think of a tree, usually the image of a majestic oak comes to mind. Standing tall, proud and ancient with a wide crown of leaves. But a low-growing mountain-side juniper with it’s spreading habit is just as much a tree as the mighty oak. Let’s find out why…

are these trees or shrubs?

Left: a stunted hawthorn growing on a mountainside. Right: Juniper, low-growing & spreading. Are they both trees?

 

WHAT MAKES IT A TREE?

Firstly, what differentiates trees from other plants? Well, a tree puts on woody growth which is permanent, where as with annual or perennial plants the shoots or whole plant dies back each year. Many of our wildflowers have to start from scratch, reproducing from seed each Spring. Whereas our trees will sit out the winter waiting for the warm weather to return.

It is the cambium layer, which lies under the bark of a tree which produces new permanent cells. As well as performing a bunch of important jobs for the tree these cells also form the woody trunk and structure of the tree. With all trees the thickness of their stems increases year on year (when healthy) which means that the diameter of the trunk and branches gradually increases. It is this annual growth which gives a tree its rings by which we can count its age.

 

WHAT IS A SHRUB?

The word “shrub” isn’t a botanical classification, but rather catch-all term for a plant which has more than one main stem, is generally less than 5 metres tall, and grows with a spreading habit.

So, the term “shrub” can refer just as much to a perennial garden bush like a hydrangea as it can to a woodland tree such as a hazel.

One of the most common examples of trees in shrub form is the hedgerow. Here hawthorn, blackthorn, hazel, holly and others are clipped back annually to form the dense, linear hedges we’re so familiar with. Hidden amongst all this there can often be species which we think of as trees such as oak, ash and sycamore, which too have been clipped back. So, does this make them shrubs or trees? I’ll let you ponder that one.

common native shrubs of the UK

3 Common Trees in Shrub Form; hazel as a coppice stool with 1 year regrowth, blackthorn with it’s early spring white blossom and elder with it’s summer flowers.

Here’s a great quote from the Reader’s Digest Field Guide to Tree & Shrubs of Britain which sums it all up;

“The difference between trees and shrubs is simple. Trees have a single woody stem, from which branches grow to form a crown. The branches of shrubs arise at ground level, forming a crown without a stem.”

But what’s truly going on here? To understand this we need to look deeper at the natural and human forces affecting whether a woody plant grows as a tree or shrub.

 

HOW SHRUBS THRIVE IN THE WOODS

In the woodland, the smaller trees which live happily in the shadow of their taller brothers (the oaks and ash of the forest) occupy the understorey. This is sometimes referred to as the ‘shrub layer’ of the woodland. These trees typically won’t grow taller than 5 metres, having found their niche in the habitat here.

Think of a woodland understorey made up of holly. Being an evergreen it sits very happily in the shade of taller trees through the summer. This is because once the leaves of oak and beech have fallen the holly can photosynthesise to its hearts content and take advantage of all that available light.

Meanwhile many shrubby trees come into flower or leaf earlier than the trees species in the high canopy. Blackthorn puts out its blossom before any other tree, ensuring that the pollinating insects give it their full attention before there’s too much competition. Meanwhile, the tiny red flowers of hazel can appear as early as December. The elder is our first native tree to come into leaf, as early as January, catching that winter sun. It’s amazing how our woods have evolved so that everyone gets their moment in the sun. There’s a beautiful interconnected poetry to it.

WHEN A SHRUB BECOMES A TREE & VICE-VERSA

So, can a shrub become a tree? Well, usually if a tree has been continually cut back then the result is a whole lot of stems. These will continue to grow in this shrubby form, though there will be some stems which die back naturally as the healthiest ones grow on, but it will always be a shrub.

In a woodland setting a hawthorn will often be in shrub form as part of the understorey. However, out in a field, where it has seeded with sufficient light and space it can grow with just one or two main stems and be very much a tree.

There are only a couple of ways a shrub can become a tree. First, when it is either deliberately pruned by us to take back its tree form, though it will always want to put out new shoots from the stool. The other route to true tree-dom is if you have a tall tree species such as oak, sycamore or beech which have been cut back in the past but then neglected for many years. These will usually form into trees, however they often still have more than one main stem. We see this in neglected coppice woodland and in over-stood hedgerows.

On the flip side through traditional woodland management like coppicing, some tree species are encouraged to grow multiple stems growing from their base (known as the stool). The regrowth of rods put out by the tree can then be harvested on an ongoing cycle. These can be made into coppice products such as charcoal, wooden furniture, firewood and turnery.

Even normally tall-growing trees like oak, ash and sweet chestnut respond well to coppicing. They can be encouraged into this shrub-like form so their multiple stems can be harvested on a 15-30 year cycle.

coppice trees and shrubs

Trees can be coppiced to produce multiple stems. Left: hazel, a common coppice tree. Right: despite having multiple stems the height & girth of this large coppiced tree is way past the point being a shrub.

SHRUBS: A DEFINITIVE LIST

Here’s a list of our common native trees that can often be seen growing in shrub form, many of which are found in hedgerows and waysides across the UK;

hazel, elder, juniper, sea buckthorn, crab apple, hawthorn, blackthorn, buckthorn, alder buckthorn, box, dogwood, guelder-rose, field maple, spindle, holly, rowan, wayfaring tree, wild privet and any of the willows.

which trees have catkins

Which Trees Have Catkins?

When out and about wandering the wilds have you noticed catkins on the trees? Depending on what time of year you’re looking they can be small and closed up or they could be large, mature, pendulous flowers, dangling like lambs tails in the breeze. They can be a very useful sign to help us identify what species of tree we are looking at.

In this blog I’ll explain what catkins are, when you can see them on different tree species and which trees have catkins. If you love trees, but struggle to tell one species from another, then you could enroll in my FREE Tree Identification Course online. More details can be found at the end of the article.

You can also get your hands on a free download; Spring Trees Catkin Guide which you can find below.

 

What Are Catkins?

Catkins are made up of a hanging spike of tiny flowers, which begin their lives all closed up but will mature and open as spring approaches. Catkins release pollen which is reliant on the wind to blow it over to a waiting flower. As a general rule, the catkins open up and mature before the leaves appear on the tree. The reason for this is so that the leaves don’t get in the way of the pollen travelling on the wind, so the chances of pollination are increased – nature’s pretty clever like that. Typically there are a lot more of the male catkins on the tree than the female flowers, again giving the tree the best chance at reproduction.

In the majority of tree species, catkins are usually male, but this is not always the case. With willow trees there are separate male and female catkins which only grow on separate trees. So they are reliant on there being the opposite sex tree within reach of the wind.

goat willow - male & female

Goat Willow (Salix caprea) has striking catkins in early Spring. The males (left) and the females (right) appear on separate trees.

When Do Catkins Appear?

On some native trees the new catkins can appear as early as the autumn, when they will be short, closed up and firm to the touch. These will hang around on the branch through winter as they slowly swell and mature. If you’re seeing these young catkins on a tree in winter then it’s most likely one of the following; alder (Alnus glutinosa), birch (Betula spp.) or hazel (Corylus avellana), these are the most common.

alder and birch catkins

Alder (Alnus glutinosa) on the left and birch (Betula spp.) on the right. Young catkins appearing in autumn.

In late winter the hazel tree’s catkins undergo a transformation as they swell in size, open up and release their pollen to the striking but tiny scarlet flowers. They are a beautiful but often overlooked splash of colour at this time of year, if you can find them. The catkins themselves are notable in late winter because they are maturing well ahead of any other native tree. Give the mature catkins a little tap and you might  well be rewarded with a cloud of pollen puffing from the flowers.

hazel catkins and flowers

Hazel (Corylus avellana) is the first native tree to give us a striking splash of colour in late winter, even if it is tiny. A country nickname for the catkins is “lambs tails”

In early spring it’s the turn of the willows and poplars to open up their catkins and this makes these species much easier to recognise than at any other time of the year. As we get to late spring, the female willow flowers have been pollinated and we get those distinctive white fluffy catkins of seeds which float on the wind and litter the pavement and curb-side, the bane of street-sweepers everywhere. I think they look quite nice though.

Here’s a list of all our native tree species which have catkins, at one time of the year or another:

Alder, Aspen, Black Poplar, Birch, English Oak, Grey Poplar, Hazel, Hornbeam, Sessile Oak, Sweet Chestnut, Willows and White Poplar

are trees male and female?

Are Trees Male & Female?

We all know how it works with animals, but can trees be either male or female? Or do they have their male and female reproductive parts on the same tree? In this article I’ll break down for you the answer to the question whether trees can be male or female and also give you some common examples you can see for yourself, out in the countryside.

The short answer to the question is… sometimes.

It’s a question I had to ask myself when doing research for creating my FREE Tree Identification Online Course. Having scoured the books and spent extensive time in the field looking at the evidence, I’ve discovered that here in the UK we have a number of native species which have separate male and female trees, although they are in the minority.

 

WORD OF THE DAY: DIOECIOUS

Trees which do have separate male and female individuals are referred to as being dioecious (pronounced dye-e-schuss), which is defined in the dictionary as “having the male and female reproductive organs, especially flowers, on different individuals.”

On the flip side, trees and plants that include the organs or flowers or both sexes on the same individual are called monoecious. The majority of native trees fall into this category, including trees like oak, birch, beech and hazel.

birch and hazel male and female flowers

Left: Birch with both male & female parts on the same branch. Right: Hazel with female flowers above and male catkins below.

In the image above you can see that the birch (Betula spp.) has female flowers (small, green and upright catkins) as well as male flowers (long pendulous and speckled catkins) on the same branch. Meanwhile hazel (Corylus avellana) has very different female and male parts on the same tree.

An easy way to remember which parts you’d expect to see on a dioecious tree is that with male trees they produce the seed (in this case pollen) which then fertilises the female trees which then grow the fruit, seed, nut or berry – sound familiar?

 

LOOKING AT EXAMPLES

So, where might you have seen a dioecious tree whilst out on your Sunday walk? Let’s talk about some examples.

Have you ever wondered why you don’t always see red berries on a holly (Ilex aquifolium) in winter? This is because only the female trees bear the fruit. It’s worth noting that there are other factors at play as well, such as whether a holly tree is getting too much shade (making it sterile) or it has no male nearby to pollinate it, so not every holly you see without berries will be a male, but EVERY holly you see with berries is a female.

holly with female berries and male flowers

Holly (Ilex aquifolium) with the familiar female berries on the left and on the right a separate tree with male flowers.

Both male and female holly trees have flowers, appearing in May, but there are subtle differences for which you might need a hand lens, so the easiest way to tell is in berry season.

 

WILLOWS & POPLARS

Once the early spring comes around there’s another two families of native trees which announce their gender, loud and proud, for all the world to see. These are the willows and the poplars. Both families of trees are closely related.

In late February and through March the willows explode with fluffy, dangling catkins. Think of the ‘pussy willow’ (Salix caprea) named after its young male catkins which look and feel like fluffy cats paws.

goat willow - male & female

Goat Willow (Salix caprea) also known as pussy willow. On the left we have the male catkins on one tree. One the right we see the female catkins on a separate tree.

Look at the yellow pollen, clearly visible on the male flowers on the left picture. Remember, this pollen is needed to fertilise the female flowers on another tree.

Meanwhile the poplars, follow suit with their own catkins. Like willows these catkins are easy to spot in early Spring as they are out before the trees come into leaf, so they really stand out. Look at the example in the picture below, we have both White Poplar (Populus alba) and Black Poplar (Populus nigra) with their striking crimson male flowers. In both cases the female flowers (also catkins) are green rather than red, so easy to tell apart once you know this.

white & black poplar - male flowers

White Poplar (Populus alba) on the left, Black Poplar (Populus nigra) on the right. Showing off in spring with their male flowers.

 

A TREE THAT BREAKS THE RULE

The ash (Fraxinus excelsior) is our third most common tree and it’s the rebel of the pack. Bending the rules – there’s always one. Look closer and in spring you could see both male and female flowers on the same tree (though on different branches) but you can also find ash trees which are exclusively male or female.

In winter, once the leaves have fallen you can often spot an ash a mile off, distinctive by its seeds, called “keys” hanging in dense bunches all in the crown. They really stand out in the overall silhouette of the tree, so look out for it. You’ll have to wait until spring though to answer the question of whether it’s male or female… or both! If you want to see pictures of both the male and female flowers of the ash, you can find these in the photo galleries of my Tree ID Course, it’s free to sign up.

So, if you’re planning some tree planting yourself and you want to include any of the species mentioned here you do need both a male and a female in order to let nature work its magic. However, if you are planting trees simply for ornament and you don’t want to encourage a young forest sprouting up around you (although personally that sounds quite nice to me) then it doesn’t matter, the tree will be perfectly healthy on it’s own.

 

BOYS & GIRLS – THE DEFINITIVE LIST

Here’s a complete list of all the native tree species which are dioecious (male or female)

Ash (sometimes), Aspen, Black Poplar, Buckthorn, Grey Poplar, Holly, Juniper, Sea Buckthorn, White Poplar, Willows and Yew
