Nicotiana glauca is a species of wild tobacco known by the common name Tree Tobacco. It is a spindly, many-branched shrub or small tree. It is distributed in warm temperate, arid and subtropical, dry and moist regions, commonly beside roadsides and along riverbanks. It is drought resistant, tolerant of a wide range of environmental conditions, out-competing native vegetation. It often forms mono-specific stands and is toxic to livestock. It is considered invasive in many parts of the world including California.
All plant parts are extremely poisonous.
