description_en: Genus of 50-80 species of annuals, often rhizomatous or stoloniferous perennials, and rarely subshrubs. They may be evergreen, semi-evergreen, or deciduous; some have attractive autumn leaf colour. They are found in a variety of habitats worldwide. Often spreading and sometimes invasive, they have usually fleshy stems and simple, entire, variably shaped, often conspicuously veined leaves comprising long-stalked basal leaves and fewer, smaller, alternate, stalkless leaves on the stems. Spikes or panicles of small, usually long-lasting, funnel-, bell-, or cup-shaped, white, pink, or red flowers are followed by distinctive, usually brownish red, 3-angled or ovoid fruits. Some of the larger perennials are undemanding plants for a border, or as ground cover, and are suitable for naturalizing in a meadow or woodland garden. Grow smaller species in a large rock garden, or at the front of a border. Contact with all parts may irritate skin; the sap may cause mild stomach upset if ingested.
