Curcuma Siam Sublime

Curcuma alismatifolia 'Siam Sublime'

curcuma siam sublime

Also known as: Siam Tulip, Summer Tulip, Hidden Ginger

Native to the tropical meadows and hillsides of Thailand, Curcuma Siam Sublime is a member of the ginger family — and a distant cousin of turmeric. Despite looking like a tulip, it's not one at all, which makes it one of the most surprising and conversation-starting plants you can grow. Its bold, cone-shaped blooms in rich deep purple rise above lush green leaves all summer long, and in Thai culture this flower has long been a symbol of new growth, hope, and prosperity. Beautiful, easy to grow, and full of meaning.

care

Plant Curcuma Siam Sublime in a warm, bright spot with indirect light and keep the soil lightly moist at all times. Feed monthly with a balanced fertilizer from spring through fall to keep those stunning blooms coming strong. Remove spent flower heads to keep the plant looking fresh and tidy. In cooler climates, bring indoors before temperatures drop and allow the plant to rest in winter — it will come back fuller and more beautiful the following season.
