Fun Facts
- 🌱 Purple Splendor and other Desert Willow cultivars are native to the southwestern United States and northern Mexico, where they grow along dry washes and arroyos, thriving in one of the harshest environments imaginable.
- 🌱 The name 'willow' refers to the plant's long, narrow, willow-like leaves, though it is actually unrelated to true willows (Salix species) and is instead a member of the Bignoniaceae family.
- 🌱 A single Desert Willow can produce hundreds of delicate seed pods in fall, each containing many winged seeds that are dispersed by wind, allowing the plant to spread naturally in its native habitat.
