View prices and availability
A tall tree with a spreading, round crown and a forked trunk. It attains a height of circa 20 m and can become over 200 years old. The bark is grey brown, later deeply furrowed and the flexible young twigs are thin and light brown. The odd-pinnate leaves have 7 - 9 leaflets and they are mat-shiny dark-green and can become 25 cm long. Underneath they are lighter with grey hairs. In autumn the leaf turns yellow. The tree has an inconspicuous inflorescence in lateral, hairy panicles in April and the yellow-green flowers are followed by 3 - 5 cm long keys. F. pennsylvanica can be applied as a park, avenue and street tree. It grows both on soils that are temporarily flooded and on drier, rich, open soils. The wind resistance is very good.
