Nicotiana glauca, commonly known as the Tree Tobacco, is a fast-growing, shrubby tree native to South America. It is widely cultivated for its ornamental foliage and tubular yellow flowers that attract hummingbirds and pollinators.

This evergreen species can reach heights of 3 to 7 meters and develops smooth, blue-green leaves covered with a waxy coating. The bright yellow, trumpet-shaped flowers appear in clusters and bloom over a long period, making it a striking choice for xeriscapes and low-maintenance gardens.

Nicotiana glauca thrives in dry, sunny locations and tolerates poor, sandy soils. It is drought-tolerant once established and grows well in USDA zones 8–11. While considered invasive in some regions, it is valued in controlled environments for its rapid growth and ornamental appeal.

Note: All parts of the plant are toxic if ingested. Handle with care and keep away from livestock and pets.

Can I grow Tree Tobacco from seeds?

Yes, Tree Tobacco is easily grown from seeds. Sow on the surface of moist soil and keep warm and bright. Germination usually occurs within 10 to 20 days.

Is Nicotiana glauca perennial or annual?

Tree Tobacco is a perennial in frost-free climates. In cooler areas, it may behave as an annual or die back in winter, resprouting in spring if roots are protected.

How tall does Tree Tobacco grow?

Nicotiana glauca can grow quickly to 3–7 meters tall, depending on climate and conditions. Its upright, semi-woody habit gives it the appearance of a small tree or large shrub.
