Description :

Amur maackia is a small, deciduous tree with a broad, rounded habit. Typically grows in cultivation at a slow-to-moderate rate to a height of 20-30′ (to 60′ in the wild). Features erect, narrow, spike-like clusters (4-6″ long) of fragrant, dull white, pea-like flowers which appear in late spring. Flowers are followed by flat seed pods (2-3″ long). Compound, odd-pinnate, dark olive green leaves (7-13 leaflets each) are attractive in summer but produce no fall color. Coppery-bronze bark exfoliates on mature trees. Genus and species names are in reference to Karlovich Maack, the 19th century Siberian explorer who discovered the tree growing in the region of the Amur River which serves as the border between Siberia and China. This member of the pea family is both closely related and similar in appearance to the slightly larger yellowwood (Cladrastis). Yellowwood has more attractive flowers and excellent fall color.

Problem :

No serious insect or disease problems. 

Garden Uses:

Grown as a small shade tree the Maackia is an excellent urban tree for its remarkable resistance to flooding and drought.
