About Siam tulip
Curcuma alismatifolia, commonly known as Siam Tulip or Summer Tulip, is a rhizomatous tropical plant from the ginger family, valued for its showy, brightly colored bracts that resemble tulip flowers. Its long-lasting 'blooms,' which can be pink, white, or purple, emerge on tall, upright stems, creating an exotic focal point in tropical gardens, containers, or as cut flowers in arrangements.
Native range
Tropical Southeast Asia (Thailand, Laos, Cambodia)
Care tips
It requires bright, indirect light; intense direct sunlight can scorch its leaves. Keep the soil consistently moist during its growing and flowering period, but drastically reduce watering when the plant enters dormancy. Use a well-draining, organically rich potting mix. Avoid waterlogging, as the rhizomes are prone to rot.
