American yellowwood

Cladrastis kentukea (klah-DRAS-tis ken-TUK-ee-ah)

Family: Fabaceae Native Canopy (>40 ft)

Yellowwood is a native tree with an open graceful, spreading crown with three seasons of interest. The hanging panicles of flowers in the spring become hanging yellow-brown fruits, and leaf color becomes yellow-orange in the fall. The smooth gray bark adds winter interest. The root system is deep, which makes transplanting difficult but allows shade-loving plants to grow underneath it. Yellowwood makes a great shade tree. Plant in average moist garden soil and protect from winter winds as branch damage may occur. Once established, it is drought tolerant. Corrective pruning is often necessary to eliminate weak branch forks. Prune only in summer to prevent bleeding. Plant this shade tree in a recreational play area or children's garden, in a meadow or woodland. It makes an excellent specimen for a winter garden or a wildlife garden as this tree not only provides nesting sites for songbirds. but high-quality pollen and nectar that attracts bees and other pollinators. Insects, Diseases, and Other Plant Problems: Verticillium wilt may occur. Limbs break easily from wind and snow. Late frosts can damage blooms.
