The method of spreading seeds in willow trees

Willows spread their seeds by the wind. The seeds of willows generally mature from April to May. The seeds are very small and have white fluff on them. They are called willow catkins because they are scattered by the wind, and willow trees rely on the flying of willow catkins to spread the seeds to the distance to take root and sprout. Also rely on the wind to spread seeds, such as poplar, dandelion and so on.
