Fun Facts
- 🌱 Silky willow gets its 'silky' name from the fine, silvery-grey hairs on the undersides of its leaves that create an iridescent shimmer when the leaves flutter in the breeze.
- 🌱 Willows can be propagated from hardwood cuttings pushed directly into moist soil, often rooting with remarkable ease—making it one of the easiest trees to propagate.
- 🌱 The genus Salix has been used medicinally for over 2,400 years; ancient Egyptians, Greeks, and Romans all used willow bark for pain relief before aspirin was synthesized.
