Another Calathea in the Prayer Plant family, the Rattlesnake Plant is native to the Brazilian rainforest, where it thrives in humid, warm, semi-shaded conditions. In Northern climates, it’s best to keep this decorative plant indoors in a sheltered area out of direct sunlight. And decorative it is; leaves are long and flame-shaped, bright green and wavy, with oval-shaped, dark green stripe-like markings. The plant gets its name from the pattern of its foliage, and the leaves become longer as the plant matures. The undersides are an equally striking reddish-purple. In the wild, Rattlesnake Plants produce bright yellow-orange flowers in early summer, though seldom indoors. Prefers somewhat sandy soil for good drainage.
