Fun Facts
- 🌱 Dwarf willow is one of the world's smallest trees and shrubs—at 1-2 inches tall, it can be completely hidden under moss or snow, yet it is technically woody and perennial.
- 🌱 In its native alpine and arctic habitats, dwarf willow grows on exposed mountaintops and tundra where it can take 30+ years to reach just 12 inches in diameter, making it an ancient living plant despite its tiny size.
- 🌱 The catkins of dwarf willow appear before most other plants have even begun to grow in spring, providing crucial early-season food for arctic insects and pollinators in harsh environments.
