The Rattlesnake Plant is a herbaceous perennial evergreen, native to Brazilian rainforests, with striking foliage and showy yellow flowers. Because it is a tropical plant and not frost hardy, it is typically grown as an indoor houseplant in most North American sites. The leaves, in particular, provide winter interest with wavy margins, purple undersides, and an alternating pattern of small and large green ellipses. The plant form is fountain-like with a spreading habit.
