Flowers on the Salix Caprea Pendula / Kilmarnock willow tree in March.
Even in full bloom, willow flowers hardly look like flowers at all. They have no petals or showy colours. Nor do they have any fragrance. Catkins or Pussy Willows usually don’t rely on pollinators to spread their pollen. Instead they simply release it into the wind, where it may or may not land on the female flower parts. In order to hit their targets, the catkins must produce a tremendous amount of pollen. (Wind-pollinated trees like these are the culprits of many a spring sneeze.)
