Harvest Tips
Kalmia Pink Charm is an ornamental shrub not typically harvested; enjoy flowers fresh in the garden or as cut branches in short floral arrangements. Cut flowering stems in morning after dew dries for longest vase life (approximately 1-2 weeks). Remove lower leaves from cut stems to prevent water-borne bacteria.
Fun Facts
- 🌱 Kalmia flowers have a remarkable spring-loaded mechanism: when pollinators land on the flower, hidden anthers snap inward and release pollen directly onto the insect's back—a strategy unique among North American native plants.
- 🌱 Mountain laurel is the state flower of Pennsylvania and Connecticut, prized for its stunning late-spring bloom displays in eastern U.S. woodlands.
- 🌱 The common name 'Sheep Laurel' (for related species) comes from the toxicity of the leaves to grazing animals; all parts of Kalmia plants contain grayanotoxins and should never be eaten or used for tea.
