Solenostemon is a genus of perennial plants, native to tropical Africa, Asia, Australia, the East Indies, the Malay Archipelago, and the Philippines. They are commonly known as Coleus, a name which derives from an earlier classification under the genus name Coleus, which is currently treated as two: with species included in either the genus Solenostemon or in another genus, Plectranthus. Species include: Many cultivars of the southeast Asian species Solenostemon scutellarioides have been selected for their colorful variegated leaves, typically with sharp contrast between the colors; the leaves may be green, pink, yellow, black (a very dark purple), maroon, and red (somewhat resembling the unrelated caladium). New cultivars with varieties of colors are constantly being made. The plants grow well in moist well-drained soil, and typically grow 0.51 m tall, though some may grow as tall as 2 meters. Coleus are typically grown as ornamental plants.
