Fla., Tex., South America (Brazil), widely cultivated throughout the tropics.

Discussion

Because of its varicolored foliage, var. bettzichiana is widely cultivated. Unconfirmed reports of its spread from cultivation include California and Maryland. Variety flavogrisea (hairy joyweed), similar to var. bettzichiana but green throughout and with oblong, ovate, elliptic, or oval leaves, has been reported from Texas, but no specimens have been seen.
