Catkin: A pendulous spike, usually of simple, unisexual flowers.*
Pussy willows, a common name which can refer to several different plants, are one of the first signs of spring. They are a type of catkin – a long cluster of many tiny flowers. The pussy willows along Wilket Creek in Edwards Gardens are coming into bloom this week.
