What is the difference between poplar catkins and willow catkins? An introduction to the latest ways to tell them apart

I. Differences

1. Different sources: Poplar catkins grow from poplar trees and are the seeds of the poplar. After the poplar flowers mature and split open, they drift out. Poplar flowers have no nectary, so they cannot secrete nectar to lure insects to spread pollen; they can only rely on the wind to spread pollen, so they are wind-pollinated flowers. Willow catkins grow from willow trees. Although they are very similar, their source is different: they are the seeds of the willow. Willow trees have unisexual flowers and no perianth, but they do have nectaries, so they can use nectar to lure insects to spread pollen, making them insect-pollinated flowers.

2. Different times of appearance: Poplar catkins generally appear first and can last for a week. Willow catkins appear later, generally after the poplar catkins.

3. Different texture: Poplar catkins have stronger cohesion and can clump together, feeling like cotton. Willow catkins have finer fibers and are more scattered and soft.

4. Different dispersal distances: Poplar catkins are mostly in clumps and are a bit heavier, so they travel shorter distances. Willow catkins are lighter and can travel farther with the wind.

II. How to suppress flying catkins

After poplar catkins and willow catkins appear, they have a certain impact on people's lives. To solve the problem of flying catkins, you can cut the trees down directly and plant other trees that do not shed flying catkins. You can also inject chemicals, which can inhibit them from producing seeds and prevent flying catkins from appearing. You can also plant only male trees, which likewise do not set seed or shed flying catkins.
