CATKINS
Catkins are special male flowers on some sorts of tree. They come out early in the year (often before the tree has leaves) and make lots of pollen that is blown away by the wind.
Catkin trees have special female flowers that, after some pollen has landed on them, will grow into seeds or nuts.
Getting pollen from one tree to another by wind works well if the trees grow close together. Trees that grow a long way apart from each other (like crab apples) have ordinary flowers that attract bees to carry their pollen.
Here are three common catkin trees:
