That such a huge and fast-growing deciduous tree as the willow grows from a tiny seed is a true miracle of nature. Little is known about the tiny seeds, so many people don't even realize what a feat they can achieve given their small size. Among other things, they make the willow a pioneer tree. Read more interesting facts about the germination and propagation of a willow here.
Willow seeds can fly very far

emergence and development
The development of the seeds happens comparatively quickly in the willow. In many willow species, catkins bloom in early spring. The resulting fruits are already ripe after four to six weeks and release the seed.
propagation of willow
Since willows are predominantly unisexual and therefore cannot fertilize themselves, they are dependent on insects. Many use an intense scent that attracts bees in particular. In areas that have a very low insect population due to the frigid climate, the wind serves as the most important pollination aid.
spread by the wind
Willow seeds often travel long distances due to their appearance. They belong to the umbrella or hair flyers. However, extensive seed production is necessary as the chances of germination actually occurring are very low. On the one hand, this is due to the tiny size of the willow seed. The small volume has hardly any capacity to transport supplies for germination. In addition, willows prefer swampy locations with damp subsoil. In the vicinity of water, the seeds threaten not to land on solid ground.
Seeds for rearing only necessary to a limited extent
True, propagation by seeds is the natural way of spreading a willow. Nevertheless, propagation from cuttings is much faster and more successful. Many tree nurseries take advantage of this. Even nature seems to have recognized this. Again and again storms tear off willow branches. If these fall to the ground in a favorable location, new shoots will quickly develop.
