distribution_en:
description_en: Genus of 100 species of mat-forming or clump-forming annuals and fibrous- or tuberous-rooted perennials from forest floors in tropical and subtropical regions of southern Africa, Asia, and North, Central, and South America. The leaves are alternate and ovate, lance-shaped, or linear. Most species root at the leaf nodes as they spread. One-sided cymes of small, saucer-shaped, 3-petalled flowers are enclosed in folded, terminal, spathe-like bracts; flowers emerge one at a time, each lasting less than a day. Use Commelina species as permanent ground cover. In frost-prone areas, grow tender species in a cool greenhouse or outdoors in an annual border; frost-hardy species are suitable for a herbaceous border.
hardiness_en: Frost hardy to frost tender; crowns of some tender species may tolerate -3°C (27°F), perhaps lower, in well-drained soil.
