distribution_en:

description_en: Genus of about 250 species of erect, bushy annuals, perennials, subshrubs, and shrubs from dry, open, and sandy habitats, including scrub, in S.W. and E. USA, Mexico, South America, Hawaii, Pacific islands, and the Canary Islands. They have simple, mostly entire, roughly hairy, and usually alternate leaves. Heliotropes are cultivated mainly for their tiny, sweetly scented, tubular flowers, which are produced in summer in clusters of coiled cymes, each forming a slightly domed or flattened flower-head. They are attractive to butterflies. Contact with the foliage may irritate both skin and eyes. In frost-prone climates, grow in a cool or temperate greenhouse, or use as summer bedding or in containers or window-boxes. In warmer regions, grow heliotropes at the front of a border or in containers outdoors.
