American yellowwood is a medium-sized tree native to the southeastern United States, reaching 30-50 feet tall when mature. Indicative of its name, the wood is yellow and encased by smooth grey to light brown bark. It has panicles of white, showy, and fragrant flowers that bloom in the spring. In the fall, it can be identified by its brilliant yellow foliage and bean-like fruits.
Yellowwood grows in full-sun to full-shade, but performs best in part-sun to part-shade with well-drained soil. It makes a great residential tree and can serve as a focal point on smaller properties or can be planted in masses in larger landscapes. Its roots grow deep into the ground making it an ideal tree to plant under. Pruning should occur in summer because the wood is prone to bleeding if pruned in late winter or early spring. There are very few cultivars of this species with the most notable being ‘Perkins Pink’ which sports light pink flowers.
Little bluestem is a prairie grass native to eastern North America that matures at 2-4 feet tall and 1.5-2 feet wide.
