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 with species included in either the genus Solenostemon or in another genus, Plectranthus. Now I do not know which this particular plant comes under.
Colours range from green, red, purple, bronze, burgundy, pink and yellow. And they make excellent ground cover and can be combined with other brightly coloured plants to make a pretty picture.
