caption_attribution_description: English: Cultivated specimen of Iochroma coccinea Scheidw. (Solanaceae) growing under glass in a border in the Temperate House, Kew Gardens, Surrey, UK. Close-up of inflorescence of scarlet, tubular flowers, for which the species received its specific name (Latin 'coccineus/coccinea/coccineum' - 'scarlet'). The species is native to Mexico. The majority of Iochroma spp. are of South American rather than Central American provenance.
context_page_description: Iochroma is a genus of about 34 species of shrubs and small trees belonging to the nightshade family Solanaceae and found in the forests of South America and Mexico. They range from Colombia to Argentina or when certain species are excluded from Colombia to Peru. Their hummingbird-pollinated flowers are tubular or trumpet-shaped, and may be blue, purple, red, yellow, or white, becoming pulpy berries. The cupular calyx is inflated in some species. The leaves are alternate, simple, and entire.
  Iochromas are cultivated as flowering ornamentals and in cooler zones make useful patio shrubs for summer display or conservatory plants. The majority are not frost-hardy and must be overwintered under protection. In warmer zones they can be used as landscape plants. They are commonly trained as standards to control their size and shape. Iochroma flowers attract hummingbirds and bees to gardens.
  Like many plants in the Solanaceae, Iochroma species contain phytochemicals with potential pharmaceutical value but the genus has not been exhaustively studied in this respect.
context_section_description: The genus Iochroma is not completely known. Several of the species listed here are known to have resulted from hybridisation in the wild and there is extensive synonymy which is not recorded here. Recent research indicates that some of the species listed here are not Iochroma (see notes) although changes in nomenclature have not formally been published. There are also known to be undescribed species.
  The genus is currently divided into three sections.
