Siam Tulip (Curcuma alismatifolia): The Tropical Ginger with Tulip-Like Blooms

Siam tulip, a member of the ginger family, produces stunning, tulip-shaped inflorescences in shades of pink, purple, or white atop tall stems. The actual flowers are small, hidden within colorful bracts. Native to Thailand, Curcuma alismatifolia goes dormant in winter, re-emerging in spring. Its broad, pleated leaves add tropical texture.

Cultivation and Dormancy

Partial shade, rich, moist, well-drained soil. Water and fertilize regularly during active growth. In fall, as leaves yellow, reduce watering and store rhizomes dry at 55-60°F, or leave in ground in zones 9-11. Replant in spring.

Uses and Varieties

Excellent as a cut flower—bracts last 2-3 weeks. Many cultivars exist: 'Chiang Mai Pink', 'White Angel', 'Siam Shadow'. The rhizomes are not edible like turmeric (Curcuma longa).
