What Are Pussy Willows, Anyway?

At the tail end of winter, fuzzy nubs start to appear along the branches of pussy willows. These soft silver tufts—as well as the plant itself—are named for their resemblance to tiny cats’ paws, and they feel so much like fur that young children often wonder if they are animals instead of plants. What are those little nubs? Are they seeds? Fruits? And why are they fuzzy?

They're actually flowers just before they fully bloom. The soft coating of hairs acts as insulation to protect these early bloomers from cold temperatures. The species most commonly called pussy willow in the Northeast, Salix discolor, is a small, shrubby species of willow that can be found dotting wetlands and moist woods throughout much of North America. Most other willows make similar flowers, and since they’re among the very first to bloom, they’re especially delightful—they signal the last throes of winter and the brink of spring.
