Description: This plant was discovered growing in the thatched roofs of farm houses where its roots were harvested to grind into the powder used in Geisha girl make-up, according to Chicago Botanic Garden which originally sent this plant to us. Obviously the plant does well in the sun and can handle some drought. But it's puzzling as to why the farmers didn't just plant it in the ground. Many thanks to Chicago Botanic Garden for sharing this plant with us.
