distribution_en:

description_en: Genus of 50 or more species of bushy, erect annuals, perennials, and subshrubs from South Africa, where they grow in sandy soils near the coast or in scrubby, often disturbed soil inland. The leaves are opposite, simple, usually linear to lance-shaped, frequently toothed. The showy, almost trumpet-shaped, 2-lipped flowers (the upper lip 4-lobed, the lower lip unlobed or 2-lobed) are borne singly in the upper leaf axils or in short terminal racemes. Annual cultivars are colourful summer bedding plants outdoors, or may be grown as short-lived, early spring-flowering container plants in a cool greenhouse. They are good for cutting. N. caerulea is suitable for a raised bed or herbaceous border, and is often used as a container plant.

hardiness_en: Frost hardy to half hardy.

cultivation_en:

propagation_en: Sow seed at 15°C (59°F) from early to late spring, or in autumn for spring-flowering container plants. Take tip cuttings of unflowered shoots from perennial species in late summer; overwinter young plants in frost-free conditions.

pests_en: Foot rot and root rot may cause problems.
