Coleus is a former genus of flowering plants in the family Lamiaceae. In recent classifications, the genus is no longer recognized, and the formerly included species are instead placed in the genus Plectranthus. Because the type species, Coleus amboinicus (Plectranthus amboinicus) is now placed in Plectranthus, Coleus is regarded as a synonym of Plectranthus. As of June 2020[update] Kew's Plants of the World Online lists both Coleus and Plectranthus as accepted genera.
The term "coleus" is often used as a common name for species formerly placed in the genus Coleus that are cultivated as ornamental plants, particularly Coleus blumei (Plectranthus scutellarioides), which is popular as a garden plant for its brightly colored foliage. This plant prefers bright, but indirect sunlight. If direct sunlight touches the plant's leaves, the colors become less brightly colored. Outside this plant needs total shade or only the most mild morning sunlight.
