Iochroma
Violetbushes are a genus of about 34 shrubs and small trees from the nightshade family, grown for their tubular blue, purple, red, yellow or white flowers. They need protection from frost and are usually grown in containers or as patio standards in cooler climates.
Iochroma is a genus of about 34 species of shrubs and small trees belonging to the nightshade family Solanaceae. Species are native from Mexico to south Brazil. They are found in the forests of Mexico and South America. Their hummingbird-pollinated flowers are tubular or trumpet-shaped, and may be blue, purple, red, yellow, or white, becoming pulpy berries. The cupular (cup-shaped) calyx is inflated in some species. The leaves are alternate, simple, and entire.
Iochromas are cultivated as flowering ornamentals and in cooler zones (zones 7–8/9) 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 (zones 9–10) they can be used as landscape plants. They are commonly trained as standards (topiary) to control their size and shape.
Several forms of Iochroma (some wild collected, some garden hybrids) have been given cultivar names. Some of the cultivars have been assigned to species but others, mainly hybrids, have not. There may be some synonymy in this list.
