Maackia amurensis, commonly known as the Amur maackia, is a species of tree in the family Fabaceae that can grow 15 metres (49 ft) tall. The species epithet and common names are from the Amur River region, where the tree originated; it occurs in northeastern China, Korea, and Russia.[1]
Amur maackia tolerates severe dryness, cold and heavy soils. More interesting than the summer flowers are the unfolding buds in spring which appear silvery and showy like flowers with frost on them.
Named for Richard Otto Karlovich Maack (Richard Maack), a 19th-century Siberian explorer who discovered the tree in the Amur River region on the border between Siberia and China.
