Curcuma alismatifolia is a beautiful exotic plant originally from Thailand. It belongs to the ginger family, but it is not edible. The Siam Tulip is the perfect plant to place in your garden to add summer interest. The large green leaves and tulip-like inflorescence can get up to 4 feet tall. They love dappled light throughout the day. The inflorescence grows on top of scapes; the bracts can be pink, red, or purple with tiny flowers that add more textural interest to the plant.
The Siam Tulip starts to go dormant anywhere from late summer to fall, depending on the variety. When the leaves begin to brown, let them dry out. Prune the leaves once they have completely dried out in the late fall. This plant will go dormant and start to pop up again in the late spring of the following year. The rhizomes can be divided about every 2 to 3 years, depending on the growth of the plant. In zones 8 and below, these make perfect container plants. Bring the plants inside to guard against freezing temperatures.
