Harvest Tips

Azaleas are ornamental plants, not harvested for food. Cut flowers for arrangements when blooms are fully open; cut stems at a 45-degree angle and place immediately in water. Deadhead spent flowers during bloom season by pinching or cutting just below the flower cluster to encourage more blooms and bushier growth.

Fun Facts

  • 🌱 The 'Pleasant White' variety belongs to the Rhododendron genus, which contains over 1,000 species and is the national flower of several countries including Nepal.
  • 🌱 Azaleas are technically rhododendrons; the distinction is mainly horticultural—azaleas typically have smaller leaves and funnel-shaped flowers, while rhododendrons have larger leaves and bell-shaped flowers.
  • 🌱 Some azalea species contain grayanotoxins, a neurotoxin found in nectar and leaves, making them toxic if ingested by humans or pets; however, poisoning is rare from ornamental exposure.
