Curcuma hybrid 'Laddawan'
This is a rare naturally occuring hybrid that was found growing in Thailand. The single plant was collected and propagated and eventually released. The name is often incorrectly spelled as ladderwan or ladawan etc. The suspected parents are Curcuma cordata and Curcuma alismatifolia. Both parents have been used to create hybrids, but they are not closely related and repeat attempts to create this cross haven't been very successful. 'Laddawan' has very good traits from each parent. A long lasting flower that is held above the foliage like C. alismatifolia, and the disease resistance and leaf and clump habits of C. cordata. It makes for an excellent landscape plant and good cut flower. It likes medium sun but can be grown in full sun. It grows to 18 inches and is hardy in USDA Zones 8-10
