Grown in USDA Zones 9-11, Nicotiana sp. (Flowering tobacco) is a small shrub that grows 2-5 feet tall and can thrive in full sun or semi-shade. It is recommended to water the plant regularly for optimal growth. The flowers of Nicotiana sp. come in various shades including pink, white, off-white, blue, lavender, purple, red, crimson, and vinous. Some varieties may also have yellow or orange flowers and some are fragrant. However, caution should be taken when handling this plant as some varieties can be toxic or poisonous and all parts contain high levels of nicotine.
When growing Nicotiana sp. in a pot in a cold region, it is best to choose a variety that is cold hardy down to at least 30°F for a short time. The pot should be placed in an area with well-draining soil and organic matter should be added. The temperature around the pot should also be monitored as it may need to be moved to a sheltered area, such as a greenhouse, during the winter in colder regions until the temperature begins to warm.
Tobacco has been cultivated in America for a long time, with some accounts dating back 10,000 years. High nicotine content varieties of Nicotiana tabacum and Nicotiana rustica were highly valued by many tribes. The flowers of the original flowering tobacco (Nicotiana alata) are very fragrant and open at night.
