Siam Tulip This tropical plant, Siam Tulip (Curcuma alismatifolia) is not a tulip but a member of the ginger family. It is an easy to grow plant indoors. It is a particularly attractive plant with beautiful foliage! They are real eye-catchers so give them a prominent place in your living room. When it is nice and warm outside, it can be stood in a sheltered spot on your patio. Do bring indoors again before the first frost.
