'''''Nicotiana glauca''''' is a species of [[Nicotiana|wild tobacco]] known by the common names '''tree tobacco''' and incorrectly also '''[[Salvadora persica|Mustard tree]]'''. Its leaves are attached to the stalk by [[Petiole (botany)|petioles]], and its leaves and stems are neither [[wiktionary:pubescent|pubescent]] nor sticky like ''[[Nicotiana tabacum]]''. It grows to heights of more than two meters.

Nicotiana glauca, Graham (N. arborea, Dietr.). Erect, tree-like, up to 20 ft. tall, glaucous-blue all over: st. branching: Lvs. long-petioled, unequally subcordate- ovate, acute, somewhat repand: fls. pedicelled, pedicels incurved in fr., in loose, terminal, bracted panicles; calyx tubular, 5-toothed. teeth acute, unequal, somewhat ciliate; corolla yellow, tube scarcely incurved, somewhat swollen above; mouth contracted, softly woolly; limb small, lobes ovate, very short, acute: caps, inclosed in the calyx. Argentina, Paraguay, Bolivia. B.M. 2837. G. 26:571.—Frequently cult, for its stately habit and striking glaucous-blue foliage which sometimes develops purplish tints. It has escaped from cult. and runs wild in Texas and Calif. Usually does not bloom in the northern states. Easily grown from seed.

'''''Nicotiana glauca''''' is sometimes referred to as '''Mustard Tree''' or '''Brazilian Tree Tobacco''' or simply '''Tree [[Tobacco]]'''. Its leaves are attached to the stalk by petioles (many other ''Nicotiana'' species have sessile leaves), and its leaves and stems are neither [[pubescent]] nor sticky like ''[[Nicotiana tabacum]]''. It grows to heights of more than 6' (2m).

Nicotiana glauca is a species of wild tobacco known by the common names tree tobacco and incorrectly also Mustard tree. Its leaves are attached to the stalk by petioles, and its leaves and stems are neither pubescent nor sticky like Nicotiana tabacum. It grows to heights of more than two meters.

Tree tobacco is native to South America but it is now widespread as an introduced species on other continents, and it is a common roadside weed in the southwestern United States.
