The male catkins are patterned green and brown, 5–10 centimetres (2.0–3.9 in) long when shedding pollen; the female catkins are green, 2–6 centimetres (0.79–2.36 in) long at pollination, maturing in early summer to bear 10–20 (50–80) capsules each containing numerous tiny seeds embedded in downy fluff. The fluff assists wind ...
Bigtooth aspens produce seeds from wind-pollinated flower clusters, known as catkins. The tree is dioecious, meaning that male and female flowers are on separate trees, which flower from mid-April to mid-May depending on the climate zone. The seed, a two-valved capsule, is distributed widely by the wind. Seed production begins around 10 years old.

The seeds of the poplar tree are easily dispersed by the wind, due to the fine hairs surrounding them. The flowers are mostly dioecious (rarely monoecious) and appear in early spring before the leaves. They are borne in long, drooping, sessile or pedunculate catkins produced from buds formed in the axils of the leaves from the previous year ...
Throughout boreal North America, Betula papyrifera (paper birch) and Populus tremuloides (quaking aspen) are successional hardwoods that frequently invade burns in black spruce. Black spruce typically seeds in promptly after fire and with the continued absence of fire eventually dominates the hardwoods.
