Cladrastis kentukea (syn. C. lutea, Koch, C. tinctoria, Raf. Virgilia lutea, Michx.). Tree, with yellow wood and smooth bark, sometimes 50 ft.: lfts. 7-9, oval or ovate, glabrous, bright green, 3—4 in. long: panicles loose, drooping, 10-20 in. long; fls. white, fragrant, over 1 in. long. June. Ky., Tenn., and N. C. —One of the most beautiful flowering native trees, with wide, graceful head and a short trunk, well adapted as single tree on the lawn. Hardy north to New England and Ont. The wood yields a clear yellow dye. There is a var. aureo- variegata with lvs. variegated with yellow.

'''''Cladrastis kentukea''''' ('''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]].

It is a small to medium-sized [[deciduous]] [[tree]] typically growing 10-15 m tall, exceptionally to 27 m tall, with a broad, rounded crown and smooth gray [[bark]]. The [[leaf|leaves]] are compound pinnate, 20-30 cm long, with 5-11 (mostly 7-9) alternately arranged leaflets, each leaflet broad ovate with an acute apex, 6-13 cm long and 3-7 cm broad, with an entire margin and a thinly to densely hairy underside. In the fall, the leaves turn a mix of yellow, gold, and orange. The [[flower]]s are fragrant, white, produced in ''[[Wisteria]]''-like [[raceme]]s 15-30 cm long. Flowering is in early summer (June in its native region), and is variable from year to year, with heavy flowering every second or third year. The [[fruit]] is a [[legume|pod]] 5-8 cm long, containing 2-6 seeds.

Plants from Alabama have the leaves more densely hairy underneath than those from further north, and are distinguished as ''C. kentukea'' f. ''tomentosa'' (Steyermark) Spongberg.

The largest specimen known is at Spring Grove Cemetery in [[Cincinnati, Ohio]], 22 m tall and 2.2 m trunk diameter; the tallest known is a slender tree 27 m tall but only 0.55 m trunk diameter, at [[Plott Cove Research Natural Area]], [[Georgia (U.S. state)|Georgia]] (Spongberg & Ma 1997; Eastern Native Trees Society).

It is widely grown as an [[ornamental tree]] for its attractive flowers, and is locally [[naturalisation (biology)|naturalized]] in many areas of the eastern United States outside of its restricted native range. It thrives in full sunlight and in well-drained soil, althought it tolerates high pH and dry soil. The Yellowwood can withstand urban settings and is attractive to birds. A number of [[cultivar]]s have been selected, including 'Perkin's Pink' (syn. 'Rosea', an invalid name) with pink flowers.

The name yellowwood derives from its yellow [[heartwood]], used in small amounts for specialist [[furniture]], [[stock (firearm)|gunstocks]] and decorative [[woodturning]].
