The leaves are alternate, 10–25 cm long and 7–12 cm broad, with an entire margin; they are green above, and glaucous below, with red veins and petiole. The flowers are produced in catkins in late spring after the new leaves appear; it is dioecious, with male and female catkins on separate plants. The male catkins are 10 cm long; the female catkins are 10 cm long at pollination, expanding to 25 cm long at seed maturity.
