Curcuma

Curcuma is a genus in Zingiberaceae family native to the warm, humid environments of south and southeast Asia. The most commercially important kind is Curcuma longa, a native of India, but widely cultivated throughout India, Ceylon, the East Indies, Fiji and Queensland for its underground stems from which, when dried and ground, the Turmeric of commerce is manufactured. In addition to C. longa, other species are grown for their ornamental leaves and flowers.

Curcuma rubescens has deep wine-purple tipped white inflorescences in the late spring which last through the emerging of the foliage. Harder to flower than others in this genus, but even without the flowers the red stems that support the leaves are very attractive. With adequate moisture it will grow in full sun and produce additional red pigment on the foliage. This is different from the another red-stemmed form, Curcuma 'Scarlet Fever', which is summer blooming. Photos taken by Alani Davis and Jay Yourch.
