Pinxterbloom is ornamental; flowers can be cut for fresh bouquets when clusters open. Harvest sprigs in early morning for best fragrance. Cut branches just above leaf nodes to encourage branching. Do not harvest more than one-third of the plant per year to maintain form and next year's flowers.
Fun Facts
- 🌱 Pinxterbloom is one of the few native deciduous azaleas of eastern North America and is the parent plant of many modern azalea hybrids.
- 🌱 The common name 'Pinxterbloom' comes from the Dutch word 'Pinksterbloem' (Whitsunday flower), referring to the time of bloom around the Whitsunday holiday in spring.
- 🌱 Unlike evergreen azaleas, this species loses all its leaves in winter, making way for stunning golden-amber fall color and an unobstructed view of flowering branches in spring.
