Yellow Birches: A Potential Landscaping Tree

Anyone looking for an out of the ordinary landscaping tree with visual appeal for cooler U.S. Department of Agriculture plant hardiness zones should consider the yellow birch. Betula alleghaniensis handles the cold associated with USDA zones 3 through 7, growing native in the Northeast, the Appalachians and into southern Canada. Many birches offer ornamental appeal via their bark, and that of the yellow birch is exceptional.

The yellow birch can exceed 100 feet in height, but most are typically much smaller. The deciduous leaves are shades of green, turning to golden yellow during the cool fall weeks. The bark gives this tree its beauty, curling up on the trunk and peeling off it in elongated, thin strips. Its color varies between amber and silvery, giving this birch winter interest and a unique appearance that differs mightily from the white bark of several other ornamental birch species like the paper birch. Wildlife will seek out a yellow birch, with animals such as moose and deer browsing on the leaves, bark and twigs. Birds will devour the seeds and smaller mammals like red squirrels and porcupines gobble up the buds, flowers and seeds.

As is the case with most birch trees, the yellow birch requires a full sun site for its best development. However, warm climates and drought are enemies of this species. Ideal soil for a yellow birch will be cool and damp. Despite an abundance of foliage, the shade this tree casts is usually light, allowing you to plant shrubs and perennials in its immediate vicinity. It is an excellent choice for the borders of woodlands, but it works equally as well in a naturalized portion of your property. One of its strengths is a palpable resistance to such common birch tree pests as the bronze birch borer and the leaf miner.

Yellow birch trees may be difficult to locate in a nursery. Yellow birches go by other names, depending upon the region of the country in which you reside, including gray birch, swamp birch and silver birch. Always ask for it by its scientific name. The sweet birch is a similar tree in that it too possesses aromatic leaves and twigs, but the wintergreen fragrance associated with the yellow birch is much fainter than that of the sweet birch.
