Calathea lancifolia
Common name: Rattlesnake plant · Rattlesnake calathea
Calathea lancifolia is a species of flowering plant in the Marantaceae family, native to the Brazilian rainforest. It is one of the most popular calatheas in cultivation, valued for its long, wavy-edged leaves patterned with alternating dark-green ovals on a lighter background and deep purple undersides. Its leaf pattern is said to resemble a rattlesnake's skin, hence the common name. It is grown as a houseplant for its decorative foliage.
