Catkins! How do I Love You?

Let me count the ways!

If there has been a personal theme this Covid spring, I would call it “seeing but not seeing”. This sounds mysterious, but I often see things, and yet don’t really take them in. Catkins are a great example. Most years, I love to find the first catkins, bring some in to enjoy, marvel at their softness. Sometime later, I may notice how the willow trees look lacy at a distance, and  how pretty that looks. But really,  before this I have considered the appearance of the pussy willows to be the main event.

With more time to explore this spring, I have visited the pussywillows and catkins just about every day, noticing not only their great variety, but how also lovely (and sometimes unlovely) they are at each stage of development and in every weather. I have photographed them with my phone, and have observed that the pussywillows most amazing to me I can’t photograph at all – these are the tiniest ones. On a rainy morning, they remind me of twinkle lights, small jewels bedecking the curves of the willows, hundreds of them. There are no pictures of them here!

This may be one of those posts I put together mostly for myself. Now that I have taken time with the pussywillows and catkins, I don’t think I will pass them by again.  Even so, behold the variety of expressions of the catkin!!

Pussy willows are dioecious, meaning there are both male plants and female plants. The pussy willows  act as insulators, for the flowers (catkins) that will eventually bloom. I am glad to know this because I saw my first pussy willows in January, during a thaw.

Usually the male catkins grow first and release their pollen. Then the female catkins grow and open shortly afterwards to receive pollen. By releasing and preparing to receive pollen at different times the tree has less chance of receiving its own pollen and a greater chance of receiving pollen from other trees. The pollen from other trees can produce stronger offspring. Willows do not spread their pollen via the wind. Instead, they rely on insects for pollination, despite having less than gaudy flowers. What they lack in visual cues, they clearly make up for in olfactory ones, producing large amounts of strongly scented nectar. Bees and flies are readily drawn to pussy willows in full bloom. One of the advantages of flowering early in spring is that there is very little competition for pollinators. The willows gain the full attention of the many bees and flies that also awaken early in the spring and are desperate for food.
