The yellowwood tree (Cladrastis kentukea) provides year-round interest, with fragrant blooms in spring, colorful foliage in spring, summer and fall, and showy seedpods that hang on during winter. The yellowwood tree provides ample shade and is an effective specimen tree. One of the more rare trees found in Wisconsin, it is native to the southern Appalachian Mountains.
The yellowwood tree is named for the color of its heartwood, which is dull
to brilliant yellow when freshly cut. The tree’s smooth, slender stems are
a lustrous reddish-brown, while older branches and the trunk are smooth and gray. The leaves emerge yellow-green in spring and turn bright green in summer. In fall, the foliage turns yellow, gold, or copper before dropping. The tree’s white flowers resemble those of pea plants and grow in long clusters. Whitish-gray, flattened seedpods develop in fall.
