Fun Facts
- 🌱 The name 'Chionoides' comes from Greek, meaning 'snow-like,' referring to the pure white flowers with delicate pink edges that resemble fresh snow with a rosy glow.
- 🌱 Azaleas and Rhododendrons are actually the same genus (Rhododendron); azaleas are simply a subgenus with typically smaller leaves and flowers and deciduous characteristics, though Chionoides is evergreen.
- 🌱 Azalea flowers are notoriously toxic to livestock and can cause serious illness; they contain grayanotoxins that affect the digestive and cardiovascular systems, so keep them away from horses, deer, and grazing animals.
