The Main Plant entry for Nicotianas (Nicotiana)

Fowering tobacco is related to the tobacco plants of commerce and bred for ornamental value.

A low rosette of large, flat, velvety leaves supports the tall flowering stems covered with many star-shaped flowers. Flower colors include white, pink, maroon, lavender, green, red, and yellow. The plants can grow up to three feet tall, but dwarf forms are also available.

Nicotiana grows best in fertile, humus-rich, moist, well-drained soil in partial shade or full sun in cooler areas. They are tough plants that will tolerate high temperatures. Transplant to the garden when all danger of frost has passed, spacing 8 to 12 inches apart.

Seeds may be sown in situ, thinning the seedlings to the right spacing. Otherwise, start the plants indoors six to eight weeks prior to planting out. Seeds germinate in 10 to 20 days at 70 degrees Fahrenheit. Don't cover seeds; they need light to germinate.

Plant viruses can be a problem. Plants that show signs of a virus, yellowed and distorted growth or ringspots on the leaves, should be pulled and thrown away. Other diseases such as stem and root rots are rarely serious and can be controlled by proper site selection and planting. Newer hybrids of nicotiana are relatively free of insect and disease problems.

Special Precaution: As a close relative of smoking tobacco and a member of the nightshade family, nicotiana plants contain nicotine and should be considered poisonous. No part of the plant should be ingested by people or animals.
