Nicotiana glauca, commonly known as tree tobacco, is a species of shrub in the nightshade family (Solanaceae). It is native to South America but has become naturalized in many other regions, including parts of North America, Europe, and Australia.

Description[edit | edit source]

Nicotiana glauca is a fast-growing, evergreen shrub that can reach heights of up to 7 meters (23 feet). The plant has a distinctive bluish-green foliage, with leaves that are oval to lance-shaped and can grow up to 30 cm (12 inches) long. The flowers are tubular, yellow, and about 5 cm (2 inches) long, blooming throughout the year in suitable climates.

Habitat and Distribution[edit | edit source]

Nicotiana glauca thrives in a variety of habitats, including deserts, coastal areas, and disturbed sites. It is particularly well-adapted to arid environments and can often be found growing in sandy or rocky soils. The plant is highly tolerant of drought and poor soil conditions, which has contributed to its spread in many regions outside its native range.

Uses[edit | edit source]

The plant has been used traditionally by indigenous peoples for various purposes. The leaves contain nicotine and other alkaloids, which have been used in traditional medicine and as a pesticide. However, it is important to note that Nicotiana glauca is toxic if ingested, and care should be taken when handling the plant.

Ecological Impact[edit | edit source]

As an invasive species in many parts of the world, Nicotiana glauca can have significant ecological impacts. It can outcompete native vegetation, alter soil chemistry, and disrupt local ecosystems. Efforts to control its spread often involve mechanical removal and the use of herbicides.

Related Species[edit | edit source]

Nicotiana glauca is related to several other species within the genus Nicotiana, including Nicotiana tabacum (common tobacco) and Nicotiana rustica (Aztec tobacco). These species share similar characteristics but differ in their specific uses and ecological impacts.
