One of the three hazelnuts we planted last spring has catkins this year!
These are the male parts of the hazelnut trees. They are actually clusters of flowers with no petals. They don’t need petals because rather than using birds or bees to carry their pollen to female florets, they use the wind. Their floppy design allows the wind to blow pollen from the male catkins to female flowers. Fun fact: pollination via the wind is called anemochory. Anemo– comes from the Greek word for wind, and chore is Greek for “I move” or “I spread.” Other trees that have catkins include alder and birch trees.
I don’t see any red buds (female florets) on the trees, yet, and I would be surprised if we get any nuts for at least another two or three years.
