Coleus, scientific name: Coleus or Coleus, is a genus of annual or perennial herbaceous or shrub plants. Some species are succulents with fleshy or lumpy tubers or roots. It is found in the tropical and subtropical regions of the Eastern Hemisphere. The relationship between Coleus, Solenostemon and Spurflower was confusing: species from the first two genera were once merged into the Spurflower genus, but the result was that the Genus Spurflower became a polyphyletic group of the Plectranthinae subfamily under the analysis of the clade affinity. The latest taxonomic treatment has re-established the genus Coleus, with 212 species from the genus Quincen, Pycnostachys and Pai vanilla, respectively; Equilabium became a genus independent of the genus Spurflower with the support of phylogenetic studies.

Coleus species are often cultivated as horticultural plants, with coleus being the most common. On the one hand, the colorful leaves of coleus make it a popular horticultural plant, and the ketogenic diet that has emerged in recent years has also made it popular because of the rich nutrients in the roots of coleus. Coleus prefers light, but is not suitable for direct sunlight, but non-direct light: because direct sunlight will destroy the pigment on the leaves, making the color of the leaves become single; Therefore, when outdoors, the coleus should be completely shaded from the light, and only the softest sunlight at sunrise.
