Plant Species of the genus Cladrastis

Information about this genus
Name: Cladrastis
Cultivation: CULTIVATION: Yellowwoods tolerate a wide range of soil types provided the drainage is good. They will not withstand extremes of soil moisture, drought or waterlogging, but are otherwise easily grown in any sunny position. The branches are narrow-forked and the wood is rather brittle, so shelter from strong winds is advisable and older trees often require corrective pruning or guying to prevent wind damage. Propagate from seed or winter hardwood cuttings.
Description: Native to China, Japan and eastern USA, this leguminous genus of 5 species of deciduous trees is cultivated mainly for its flowers, which are carried in wisteria-like racemes opening from early summer, followed by flat seed pods. The pinnate leaves, usually around 12 in (30 cm) long, have fine hairs on the undersides of the 4 in (10 cm) long leaflets. They are known as yellowwoods after the American species Cladrastis lutea, both for the color of its timber and the yellow dye it yields. The heartwood is used for gunstocks, especially those with carved detailing.
