Fun Facts
- 🌱 Mollis azaleas were originally bred in the 19th century in Belgium and Germany by crossing Rhododendron molle (Chinese azalea) with Rhododendron simsii (Indian azalea), creating the spectacular hybrid 'Mollis' group known for their vibrant colors and fragrance.
- 🌱 The rose-pink flowers of 'Kermesina Rose' bloom before the leaves emerge, creating a dramatic spring display where the shrub appears to be made entirely of flowers—a phenomenon called 'precocious flowering.'
- 🌱 Azalea flowers contain a substance called grayanotoxin in their nectar, which can be toxic if ingested in large quantities, though ornamental cut flowers are safe to display indoors (just not to eat).
