Blood red spiral ginger

Description:

Costus is a genus of perennial tropical herbaceous plants from the costus family (Costaceae). They are often characterized and distinguished from relatives such as Zingiber (true ginger) by their spiraling stems. The genus as a whole is thus often called spiral gingers, but this can also refer to C. barbatus specifically. source: http://en.wikipedia.org/wiki/Costus
