Overview

Nicotiana spp. is a genus of about 70 species in the nightshade family (Solanaceae), including annuals, short-lived perennials, and a few shrubs and small trees, native mainly to the Americas with a smaller group in Australia and the South Pacific. Most are upright, sticky-haired plants 1-10 ft (0.3-3 m) tall, with large, soft, oval basal leaves and smaller leaves up the flowering stems. The tubular flowers, 1-4 inches (2.5-10 cm) long, flare into five lobes at the mouth and come in white, green, yellow, pink, red, and maroon; many open toward evening and release a strong scent that draws night-flying moths. The genus includes cultivated tobacco (N. tabacum), grown for its leaves, and ornamental flowering tobaccos such as N. alata and N. sylvestris. All parts contain nicotine and related alkaloids and are poisonous if eaten by people or animals. Most ornamental species are grown as warm-season annuals because they are frost-tender, and the sticky foliage can collect dust and small insects.

Native Range

Native mainly to the Americas, especially South America, with a separate group of species in Australia, New Caledonia, and other South Pacific islands. Cultivated tobacco and several ornamental species are now grown worldwide.

Suggested Uses

Ornamental flowering tobaccos are grown in summer borders, containers, and night gardens for their long tubular flowers and evening scent. The evening fragrance suits seating areas and entryways used after dark. Because all parts are poisonous, the genus is placed away from areas used for food crops or grazing.

How to Identify

Recognized by upright, often sticky and hairy stems carrying large soft leaves and clusters of long tubular flowers that flare into five lobes. The flowers are commonly white, green, or pink and many are night-scented. The soft, glandular foliage and trumpet-shaped, five-lobed flowers separate Nicotiana spp. from other nightshades such as Petunia spp., which are lower and more branching.

Summer Fall

Ornamental species flower over a long warm-season span, from early summer to autumn (June-October) and until frost. Many flowers open or release scent in the evening and are pollinated by moths, while some day-open forms draw bees and hummingbirds. Removing faded flowers extends bloom on annual types.

Care & Maintenance

Care Guide

Grow in full sun to part shade in fertile, moisture-retentive but well-drained soil with steady summer water. Most ornamental species are frost-tender and grown as annuals, sown indoors and set out after the last frost, while a few perennials survive winters in USDA zones 8-10. Tall species such as N. sylvestris may need shelter from wind or light staking. Hot, dry soil cuts flowering short, and the sticky leaves can hold aphids and whitefly. All parts are poisonous if eaten, containing nicotine and related alkaloids. Plants often self-sow, returning from seed the following year in mild climates.

Pruning

Faded flowers are removed through summer to prolong bloom and limit excess self-sowing on annual species. Tall stems are cut back if they flop or finish flowering, which can prompt a fresh flush on perennial types. Annual plants are pulled out after frost kills them.
