description_en: Genus of about 200 species of bushy annuals and perennials from moist, open forest areas in tropical and sub-tropical Central and South America. They are grown for their colourful leaves, which are opposite, linear to obovate, often toothed, and variable in size. They bear insignificant flowers in terminal or axillary spikes. In frost-prone areas, use as annuals in summer bedding, or grow in a cool or temperate greenhouse or conservatory; they are excellent for hanging baskets. In frost-free climates, use for bedding or as ground cover.
