January 31st – One of the sure signs of a change in season from winter to spring is the appearance of various types of catkins, which are most commonly seen at this time of year on hazel trees, or in the case of these long ones, alder.

Alder is curious in that the buds you can see are also flows, the large blooms are male, and those female.

The word catkin is likely to have come from the Dutch Kateken, meaning kitten – due to the resemblance to kitten’s tails.

Catkins emerge this time of year as they’re wind pollinating, and emergence after coming into leaf would hamper pollination.
