Maackia amurensis, or Amur maackia originates from a region of the Amur River which serves as a border between Siberia and China, and owes its name to the Siberian explorer Karlovich Maack. Despite its non-native roots, Amur maackia grows in USDA hardiness zones 3-7 and is thus tolerant of a myriad number of climates but prefers full sun and moist, well drained soils. It is also tolerant to drought conditions. A small and compact deciduous tree reaching heights of merely 30 to 40 feet tall, Amur maackia is commonly seen adorning yards and streets in urban environments. Even this height is a long process as it only grows around 12 feet in the span of twenty years. However, what it makes up for in size, it recovers in aesthetic appeal.

Aside from its compact form, Amur maackia is also known for its aesthetic appeal all throughout the year. In the winter, its bark provides a stark contrast from the dull colors of other trees due to its distinct exfoliating copper green bark. With the commencement of spring, this tree stands out from others because its new leaves take on a silvery appearance, owing to the silky hairs covering them.

Maackia amurensis has compound dark green leaves that are 8-12 inches in length, and is a member of the Fabaceae or pea family. As a result, it has fruit in a flat brown pod that is 2-3 inches in length. These pods show themselves in mid summer after the tree’s showy white flowers are pollinated by bees in late spring. These flowers appear in upright clusters with a light fragrance.
