The Story

Curcuma longa, commonly known as turmeric, is a perennial rhizomatous herb with broad, lance-shaped leaves and clusters of bright yellow flowers that resemble small, torch-like structures, thriving in tropical climates. The 'Emperor' cultivar is distinguished by its large, tropical green leaves with a wide, dark purple central stripe, and tall spikes of showy, rosy-pink bracts in late summer.
