COUNTRY OF ORIGIN AND NATIVE HABITAT
Amur maackia is native to Manchuria (northeastern China and Korea). Trees are found in open woods and scrub in full sun and a variety of soils. Amur maackia can grow up to 40 ft. tall in the wild. Maackia contains around 6 species distributed throughout eastern Asia. The Fabaceae family also contains redbud, black locust, and honey locust. Members of the Fabaceae family enrich the soil by adding nitrogen.

Growth Habit and Form
Amur maackia is a small and rounded, deciduous tree with arching, spreading branches. It grows 20 to 30 feet tall and wide under cultivation.
The dark green leaves are alternate, compound, odd-pinnate with 7 to 11 leaflets. Individual leaflets are elliptic and 1 ½ to 3 ½ inches long. Leaves are silvery-gray when unfolding. Leaves do not develop appreciable fall color; the green leaves drop soon after the first freeze.
Creamy-white, pealike flowers appear in 4 to 6 inch long upright and dense, showy clusters in June or July. Their fragrance is similar to that of freshly mown grass or alfalfa. Flowers are pollinated by bees.
Fruits are flat, brown pods that are 2 to 3 inches long and 1/3 to ½ inch wide.
The shiny, coppery-brown bark peels with age into loose flakes and curls.
