Pussy Willows Peeking Out

3-27-19 pussy willow_U1A5143Nothing announces the arrival of spring more than willow flowers peeking their silver heads out of the bud scales which have surrounded and protected them all winter. What we call pussy willows are, in fact, the soft, silvery hairs that insulate the emerging spike of flowers, or catkin, within a willow flower bud. Pussy willows are dioecious, meaning there are both male plants and female plants. A male willow has only male catkins; female willows have only female catkins.

An individual willow catkin consists of all male or all female flowers. The first catkins to emerge in the spring are usually males. The hairs, or “pussies,” that emerge when willow buds first open trap the heat from the sun and help warm the center of the catkins, where the flowers’ reproductive parts are located. This trapped heat promotes the development of the pollen (or in female flowers, the ovules) of the flowers deep within the hairs. Eventually the reproductive parts of the willow flowers – the stamens and pistils – emerge, but until they do, we get to enjoy their silvery fur coats.
