Nicotiana sylvestris aka Ornamental Tabacco

Nicotiana sylvestris belongs to the nightshade family, Solanaceae. Its native range runs from Bolivia to northwest Argentina. Common names include woodland tobacco and flowering tobacco. This tender plant can live as a biennial or short-lived perennial. Gardeners grow it as an annual where winters are cold. It forms a leafy base, then sends up branching stems.

Plants reach about 3–5 feet (0.9–1.5 m) in gardens. They spread about 1–2 feet (0.3–0.6 m). The upright stems may need stakes for support. Dark green leaves form a rosette at ground level. Their shapes range from oval to oblong or spoon-shaped. The coarse leaves feel rough to the touch. Sources give leaf lengths of about 1–1.25 feet (0.3–0.38 m). The plant sheds its leaves rather than keeping them year-round.

Clusters of white flowers rise above the broad leaves. Each bloom has a long tube and a star-like mouth. Flowers can reach about 0.3 feet (0.09 m) long. They have a sweet scent that suits planting near paths. Bloom starts in June and can last until frost. Remove faded flowers to help keep new blooms coming. The flowers draw hummingbirds, butterflies, and moths. Their pale blooms and scent suit gardens enjoyed at night.

Choose sun or part shade and shelter from harsh exposure. Afternoon shade helps in hot southern gardens. Use rich soil that stays moist but drains well. The plant accepts acid, neutral, or alkaline soil. RHS lists clay, chalk, and loam as suitable soils. It gives a UK hardiness rating of H2. NC State lists USDA zones 10–11. RHS also reports outdoor survival in some mild UK gardens. There, roots may regrow after brief drops to 23°F (-5°C). A dry winter mulch helps protect these plants. Seeds provide a means of propagation, and plants can self-sow.

Use this plant in borders, cottage gardens, or wildlife plantings. Place it near patios or walks to enjoy the scent. Routine pruning is not needed, though stems may need support. Aphids and beetles can cause trouble. Other possible pests include thrips, whiteflies, and glasshouse leafhoppers. Grey mould and virus diseases may also occur. Avoid planting near tomatoes, potatoes, peppers, or eggplants. These crops can share tobacco mosaic virus and other diseases. This is not a food plant: eating it can harm people and dogs. Avoid skin contact, and wear gloves when handling it.
