Propagation
Sow seed when ripe in a prepared bed or stratify seeds in a moist sandy soil, then place in a shaded position. Seedlings should be transplanted the following year.

Soft tip cuttings of non-flowering shoots during summer.

Botanic information
Leaf: The leaves are deltoid to ovate up to 60 mm (2⅜ in) wide with a rounded base and a long acuminate apex. The petiole is up to 25 mm (1 in) long and the shiny upper surface is glabrous and the underside is pubescent on the veins.

Flower: The slender pendulous male catkins appear during autumn and open in early spring with the new leaves. The pendulous cylindrical greenish female catkins are up to 40mm (1⅝ in) long and disintegrate with the ripe fruit.

Fruit: The pendulous catkin is up to 40mm (1½in) long with broader angular scales that are pubescent on the margins and has a long stalk. The tiny nut is narrower than the broad wing. The seeds are viable but the plant may be reproduced vegetatively.
