How to identify our most common tree seeds

Hello! In this tutorial, we are going to learn how to identify our most common tree seeds . Are you ready? Lets get started!

Ash seeds (keys)

Ash seeds have a 'seed' at the top, and a long, thin papery wing underneath. They dangle in bunches from the branch tips.

Field maple

Field maple seeds are wide, large and stick out horizontally when in their pairs. They are often tinged with pink.

Hornbeam

Hornbeam seeds consist of a seed at the top, nestled between a three-lobed papery wing around and underneath.

Linden

Linden seeds grow in small clusters of 2-4 at the tip of the stem, which is wrapped around by a light, membranous leaf.

London plane

London plane seeds are small, tufted seeds, which grow in fuzzy balls, dangling beneath the branches.

Norway maple

Norway maple seeds are medium sized, frilly round the edges and grow in pairs, which stick out diagonally.

Pine

Pine seeds come in different shapes and sizes, but have a seed at one end, and a larger, thin, papery wing.

Sycamore

Sycamore seeds are small, and grow in pairs that hang close together, with the seeds at the top and wings beneath.

Wych elm

Wych elm seeds consist of a flat, round seed nestled in the middle of a flat, round, thin, membranous wing.

What are seeds?

Seeds are basically the babies or offspring of parent trees. They are produced following pollination of the trees' flowers and contain all the genetic material of the tree. Inside, they have a supply of food and nutrients ready to start their journey into new trees and in fact, they are specially adapted to disperse away from their parent trees by flying, floating, bouncing or rolling away (or being eaten and taken away - sometimes inside a juicy fruit!) This helps them find the space to grow and mature without competing with their parents for water, nutrients and sunlight.

Which trees have nuts and seeds?

There are many sizes and shapes of tree seeds, but usually, we only notice the larger sized seeds. The nine seeds you are likely to notice on your nature walks: ash, field maple, hornbeam, linden, London plane, Norway maple, pine, sycamore and wych elm. Some of the smaller seeds you might come across, are alder, birch and willow.

The six most common 'nut' producing trees, are: beech, hazel, horse chestnut, oak, sweet chestnut and walnut. You can learn to identify our most common nuts here.

How to identify our most common helicopter seeds

Identifying Helicopter Seeds

In this tutorial, we will learn about how to identify helicopter seeds.

Here in Ireland and the British Isles, you are most likely to find the following helicopter seeds:

Field maple
Norway maple
Sycamore

These three seeds may look very similar, but there are some easy ways to tell them apart. So, let's take a look and learn a bit about them.

How to identify our helicopter seeds

Field maple seeds

Field maple seeds have the greatest angle of the three and grow almost horizontally away from each other. Each seed is curved in an upward scoop from the bottom.

Norway maple seeds

Norway maple seeds also grow far apart from each other, but at a closer angle than field maple seeds. Each seed is broad at the tip and has a wavy appearance to its edges.

Sycamore seeds

Compared to field maple and Norway maple, sycamore seeds are smaller and they grow much closer together. Each seed is rounded at the tip and curves outwards at the bottom.

What are helicopter seeds?

Have you ever asked yourself, what are helicopter seeds and why do they have wings?

Well, there are two types of flying seed - parachute seeds and winged seeds. Helicopter seeds are winged seeds. Their wings are single, stiff, flat membranes, which are attached to the actual 'seed' bit and designed to help the seed catch the wind as it falls from the tree and fly away. Theis helps it move away from its parent tree so it is not competing for food, water and sunlight.

The reason they are called helicopters is because of the way they spin as they fall from the tree. But, they have other names too, including spinning jennies, whirligigs and whirlibirds. But their proper name is a samara.

Have you ever wondered why maple seeds spin as they fall ? You can find out here.

Summary

Well, I hope you have enjoyed learning all about helicopter seeds? Do you remember their names? They are:

Field maple
Norway maple
Sycamore

We also learned about why they have wings, what their wings are, and some other names for them too.

Helicopter Seed Nature Study

Now it is time for your helicopter seed nature study. Are you ready?

Your task, is to go out on a nature walk and try and find all three of the seeds we have just learnt about. I want you to:

Examine the shape of their wings
Look at the angle between the two wings in a joined up pair
Feel the texture of the wing around its different sides
Notice the size, shape and location of the 'seed' relative to the wing
