Little ruby

''Alternanthera dentata'', known as little ruby and ruby leaf alternanthera, is a fast-growing ornamental groundcover plant in the amaranth family. Native to the West Indies and Brazil, the plant is chiefly grown for its coloured foliage. It is one of the dozen synonyms of ''Alternanthera brasiliana'', and is alike in appearance with ''Alternanthera bettzickiana'', which all have strikingly similar looking cultivars.
