View prices and availability
This form of P. amurense grows to a medium-size eventually large tree. The crown is somewhat narrower and more regular in shape than P. amurense. The year-old twigs are reddish brown, an older bark light brown-grey with deep cork grooves. The large imparipinnate leaves have leaf segments that vary in numbers from 5 to 13. The leaf segments are oval-elliptical to elongated and 5 to 10 cm long. The leaf is matt yellow-green on top and light green on the underside. Especially young leaves have soft hairs on the underside. The green-yellow flower panicles are 6 to 8 cm long and wide and appear in June. In autumn the leaf turns yellow first then falls early. The fleshy, shiny black berries remain on the tree throughout winter.
