description_en: Genus of about 67 species of erect, frequently rosette-forming annuals, biennials, perennials, and shrubs from Australia, North America, and tropical South America, where they grow on mountain slopes and valley floors, often in moist soils. They have alternate, linear or oblong-lance-shaped to broadly ovate, glandular-hairy leaves. The flowers are tubular to trumpet-shaped or salverform, occasionally scented, and borne in racemes or panicles, usually over long periods in summer, sometimes in autumn. Flowers usually open only in the early evening and at night; flowers of some cultivars remain open during the day if sited in partial shade. Cultivars derived from N. alata and N. x sanderae are ideal summer bedding annuals, their upward- or horizontally-facing blooms remaining open in full sun. Grow N sylvestris in a mixed border or semi-wild garden. Contact with the foliage may irritate skin.

hardiness_en: Frost hardy to half hardy.
