Nicotiana glauca, commonly referred to as Tree Tobacco, is a type of wild tobacco characterized by its slender, multi-branched structure, resembling a small tree or shrub. This species thrives in warm temperate zones, arid climates, and subtropical regions, often found flourishing along roadsides and riverbanks. Notably drought-resistant, it can adapt to a variety of environmental conditions, frequently outcompeting local flora. Tree Tobacco tends to establish dense, single-species populations and poses a toxicity risk to livestock. Its invasive nature has led to concerns in numerous areas worldwide, including California.
Every part of this plant is highly toxic.
