Cladrastis kentukea, the Kentucky yellowwood or American yellowwood (syn. C. lutea, C. tinctoria), is a species of Cladrastis native to the Southeastern United States, with a restricted range from western North Carolina west to eastern Oklahoma, and from southern Missouri and Indiana south to central Alabama. Also the tree is sometimes called Virgilia.
The common name refers to the yellow coloration of the heartwood, which later becomes light brown after it has been cut and dried. It was used to make gunstocks, small decorative furniture, and other specialty items. Yellow-Wood is an unusual tree with smooth bark, showy flowers, and attractive fall coloration. Therefore, it should be cultivated more often.
