Nicotiana is a genus of herbs and shrubs in the nightshade family, best known as the source of commercial tobacco (N. tabacum), with ornamental species grown as flowering tobacco. In cool climates most behave as annuals, and the key to growing them is full sun to part shade with evening-scented flowers.
Family
Solanaceae (Nightshade family)
Light
Full sun, Part shade
Water
Water regularly so the soil stays moist but not waterlogged, especially in hot weather.
Soil
Well-drained, fertile garden soil or a good potting mix.
Temperature
18–30 °C; protect below 5 °C, as they are frost-tender annuals in temperate areas.
How easy
Easy
Safety

About
Nicotiana () is a genus of herbaceous plants and shrubs in the family Solanaceae that is indigenous to the Americas, Australia, Southwestern Africa and the South Pacific. Various Nicotiana species, commonly referred to as tobacco plants, are cultivated by humans.
N. tabacum is grown worldwide for the cultivation of tobacco leaves that are used for manufacturing and producing tobacco products, including cigars, cigarillos, cigarettes, chewing tobacco, dipping tobacco, snuff, snus, etc.
How to grow it
Several species of Nicotiana, such as N. sylvestris, N. alata 'Lime Green' and N. langsdorffii are grown as ornamental plants, often under the name of flowering tobacco. They are popular vespertines (evening bloomers); their sweet-smelling flowers opening in the evening to be visited by hawkmoths and other pollinators. In temperate climates, they behave as annuals (hardiness 9a–11).
The hybrid cultivar 'Lime Green' has gained the Royal Horticultural Society's Award of Garden Merit.
Where it grows
Despite containing enough nicotine and/or other compounds such as germacrene and anabasine and other pyridine alkaloids (varying between species) to deter most herbivores, a number of such animals have evolved the ability to feed on Nicotiana species without being harmed.
