What Type Of Leaf Is A Birch Leaf?

Birch trees have simple, serrated leaves, arranged alternatively on the branches. Their shape and size may vary according to the birch species. Read on to know more about birch tree leaves and characteristics.

 

We cover some specific varieties like white birch leaf identification, silver birch and birch’s other identifying features like flowers and bark.

 

Shape

The first factor to consider in identifying a birch leaf is its shape. The shape of the leaf is somewhat egg-shaped or triangular with a rounded base.

 

It has serrated margins and a pointed tip. You may notice subtle differences in the shape of the leaf in different birch species.

 

For instance, the grey birch tree has triangular-shaped leaves whereas the river birch tree leaf identification is done on the basis of their diamond shape. The white birch tree has oval leaves marked by rather pronounced teeth on their margins while the sweet birch comes with oblong leaves.

 

Size

Unlike the foliage of maple and oak, birch tree leaves are not really large. The size of the birch leaf may also vary according to the variety. For instance, species like yellow birch and sweet birch may have longer leaves (more than 4 inches) whereas with white birch leaf identification, you may notice that they have shorter leaves (2 to 3 inches).

 

The foliage of Yukon birch is among the smallest of birches and rarely grows more than 1.5 inches in length.

 

Venation

Learning about venations can also help you in birch tree leaf identification. Birch leaves have pinnate venation, i.e., the secondary veins are arranged parallel to each other and run from the midrib towards the margin of the leaf.

 

What color leaves are on birch trees?

The usual color of a birch tree leaf is glossy green. Come autumn, and the leaves turn into attractive shades of yellow and gold. Their fall foliage is one of the main reasons why birch trees are often planted as an ornamental specimen in gardens and yards.

 

The colors of birch tree leaves may differ according to the birch species. For example, for paper birch leaf identification you must know that this species has leaves that are dark green on top and duller green at the bottom. The leaves turn bright yellow in the fall.

 

For black birch leaves, all you need to know is that this species has long, shiny green leaves that can be elliptical to ovate in shape.

 

Other features

Here are a few other things you should know about birch tree leaf identification. Birch tree leaves sport a short stem and have a prominent series of veins. The leaf margins usually have unique toothlike projections that are more noticeable in some of the species like yellow birch and water birch.

What Do Silver Birch Leaves Look Like?

Silver Birch (Betula pendula or B. verrucosa) is a popular Birch variety. It starts growing as pyramidal but changes to rounded at maturity. This medium-sized, deciduous tree can be anywhere between 40 to 80 feet tall, depending upon its growing conditions.

 

The main feature in birch leaf identification in case of silver birch is that this species has triangular-shaped leaves. With its light canopy, drooping branches and exfoliating white bark (with scattered black fissures), the silver birch looks strikingly elegant.

 

As the tree grows older, its bark becomes more rugged.

 

What Is The Leaf Arrangement Of A River Birch?

To know more about river birch tree leaf identification, you should be aware of the leaf arrangement of this unique birch. This ornamental variety of birch features wedge-shaped leaves that are glossy and dark green in color.

 

The leaves are evenly doubly serrated and have hairy veins on the lower side. The simple leaves are arranged in an alternating manner.

 

We’ve talked about black birch leaf identification, silver birch, and other varieties. No, lets move forward to its flower type, fruits, and bark.

 

Birch Tree Flowers

The small conelike clusters of flowering spikes spotted on a birch tree are known as catkins. Birch trees are monoecious, i.e. separate male and female flowers are found on the same tree. While the male birch flowers are bigger and drooping, female flowers are smaller and upright. These flowers blossom in the springtime and disintegrate at maturity and release small, single-seeded nutlets.

 

Birch Tree Fruits

 

The fruit of a birch tree is a small nut or winged samara. The wings, however, may be obscure in some of the birch varieties. The fruit releases about a million seeds each year.

 

Birch Tree Bark

Now that we have covered river & paper birch leaf identification, let’s talk about birch tree bark. Other than its attractive foliage, birch trees are also known for their splendid, papery textured barks.

 

The color of birch bark can be white, whitish-grey, blackish, silver or even red, depending upon its variety. It features dark, long, horizontal streaks known as lenticels. Owing to the marking caused by these lenticels, the birch bark flakes and peels off easily.

 

This peeling nature of birch barks adds to their ornamental charm during the winter months. However, not all birch trees have papery and peeling bark.
