Types of Birch Tree Leaves: Identification Guide With Pictures
Birch tree leaves are known for their distinctive shape, texture, and veining patterns. Birch tree leaves are generally triangular or diamond-shaped with serrated margins, prominent veins, a slender petiole, and pointed tips. While birch tree leaves share common features, variations in their appearance aid in identifying distinct species.
This article is an identification guide to the different types of birch tree leaves. Descriptions and pictures of the leaves of various birch tree species will help you identify and distinguish between different types of birch trees.
How to Identify Birch Tree Leaves
To identify a birch tree by its leaves, look at the leaf shape, margin, veins, and color. Birch leaves are typically egg-shaped or triangular with a rounded base. Next, look at the serration along the edges. Lastly, look closely at the veining pattern and differences in color between the top and bottom surfaces.
Generally, birch leaves have a glossy sheen on the upper surface. They are arranged alternately on branches and measure 2” to 3” (5 – 7.5 cm) long. However, leaves on the yellow birch and sweet birch tree can grow up to 5” (10 cm) long.
Types of Birch Tree Leaves: Identification Guide With Pictures
Let’s look in more detail at the identifying features of the most common types of birch tree leaves you will likely come across.
Silver Birch Tree Leaves (Betula pendula)
Silver birch tree leaves are distinctive triangular leaves with doubly serrated edges. Identifying features of the deciduous leaves are their long, tapered tips, glossy green texture, and prominent veins running laterally from the midrib. Silver birch leaves are relatively small, measuring 1.5” to 3” (4 – 7.5 cm) long with heart-shaped bases.
The upper side of silver birch tree leaves is a vibrant, glossy green. In the fall, the birch leaves turn a golden yellow color before dropping. The leaf underside is lighter and may be covered in fine hairs.
Other identifying features of the silver birch tree are its white, papery bark, pendulous or drooping branches, and greenish cylindrical clusters of flowers. Silver birch trees grow 30 to 50 ft. (10 – 15 m) tall and grow in a wide range of soil conditions.
Paper Birch Tree Leaves (Betula papyrifera)
Paper birch tree leaves are large, slender triangular blades with coarsely serrated margins. The birch leaves are also known for their ovoid shape with a tapering tip and glossy green texture. Additionally, the birch leaves have distinct veins running from the midrib to the teeth and a hairy underside.
Paper birch leaves measure 2” to 4” (5 – 10 cm) long.
The paper birch leaves are dull green with a shiny upper side in spring and summer. The leaves turn a golden yellow in the fall before dropping to the ground. Like all types of birch trees, the leaves are arranged alternately on branches. Compared to silver birch leaves, paper birch foliage is more slender with a deeper green color.
Apart from the triangular or egg-shaped, pointed leaves, the paper birch’s other features are its exfoliating white bark revealing orange inner bark, drooping cone-like flower clusters, and small, winged seeds.
River Birch Tree Leaves (Betula nigra)

Birch Trees vs. Aspen Trees
Distinguishing between aspen and birch trees can sometimes be confusing due to their slender trunks, whitish silvery bark, and yellow autumn foliage. However, it’s important to note that aspens (genus Populus) and birch trees (genus Betula) belong to different plant families. Besides their family classification, there are additional contrasts in terms of bark and leaves that set aspens and birch trees apart.
What’s the Difference Between Aspen vs Birch Tree Leaves?
When comparing leaves of aspen and birch trees, there are distinct characteristics that set them apart. Aspen trees have flat, rounded leaves with a pointed tip and serrated edges. These leaves are wider, rounder, and shorter in comparison to birch leaves, displaying a finer toothed structure. Conversely, birch trees have lanceolate leaves that create a distinctive “V” shape, differing from the flatness of aspen leaves.
Birch vs. Aspen Tree Bark
You can also tell apart birch and aspen trees by their bark. Aspen bark becomes rough and fissured as the fast-growing tree matures. Birch tree bark is thin and papery and, unlike aspen trees, easily peels.
