River Birch - Betula nigra
River birch (Betula nigra) has become one of the most popular birches planted in North America. This deciduous tree is native to the eastern United States, where it grows along rivers and streams, which is how it got its name. The tree's branches form an arching, expanding canopy overhead, and it's often grown with several trunks. It makes a graceful shade tree for a yard, a park, or a wet corner where other trees struggle.
The River Birch Changes With Every Season
The river birch’s tender, bright green leaves are displayed in the spring. Summer brings full canopy, providing broad, cool shade from the hot midday sun. In autumn, the whole tree turns golden yellow. Even in winter, its bare branches stand out against the sky, and its peeling bark gives you something to admire on the grayest days.
Leaves, Seeds, and Wildlife Support
The leaves of the river birch are diamond-shaped, with double-toothed edges, a dark green top, and a paler underside that flashes when the wind turns it over. These leaves feed the caterpillars of several native butterflies and moths, which in turn feed songbirds. Unlike most birches, the tree drops its tiny seeds in the spring, and finches and other small birds pick through them.
Unique Bark and Foliage
One of the most impressive features of the tree is its bark, which comes in shades of salmon, cinnamon, and cream and peels away in thin, papery curls. On older trunks, the bark near the base turns darker and rougher.
River Birch Tree for Sale: A Popular Choice for Urban Landscaping
The river birch is widely used among landscape architects as a garden or park tree and in urban landscaping. It's a natural fit near a pond or stream, in a rain garden, or along a bank where its roots help hold the soil in place. It also handles heat better than other birches and resists the bronze birch borer, a beetle that kills many white birches.
Looking for a river birch tree for sale? TN Nursery ships it bare root in 1-2, 2-3, and 3-4 foot sizes. Before you order, walk your yard and look for that low, soggy spot where nothing else wants to grow. That's often the perfect home for it.
River birch grows in USDA zones 4 through 9 and reaches 40 to 70 feet tall and 40 to 60 feet wide. It's a fast grower, often adding two feet or more a year when young. Give it full sun to partial shade and moist, acidic soil. It handles wet feet and even short floods. In alkaline soil, though, the leaves turn yellow and the tree struggles. During long, dry summers, it may drop some leaves and twigs, so plant it at least 20 feet from your house and away from spots you'd rather keep tidy.
Bare-Root Planting and Care
This plant ships bare root, so plant as soon as the box arrives. Soak the roots for a couple of hours, set the tree with the root flare right at soil level, and water it in well. Spread mulch in a wide ring, keeping it a few inches from the trunk. River birch is a thirsty tree, so don't let the soil dry out that first summer. Soak it deeply whenever the top feels dry. Once its roots take hold, it grows fast.
