Quizplus · Accepted Answer

Cottonwood, aspen, and willow trees are known for their wind-pollination strategy. The absence of petals on their flowers and the timing of flowering before the leaves emerge are adaptations to enhance the effectiveness of wind dispersal of pollen. This allows the pollen to be more easily caught by the wind and carried to other trees without the obstruction of leaves.
