Perennial shrubs or small trees to 4 m, pubescent with simple, non-glandular hairs, without spines. Leaves alternate, simple, entire or lobed, petiolate. Flowers solitary in forks of stems, bisexual, actinomorphic, pendent. Calyx tubular, the lobes 2-5, sometimes spathe-like,either falling as a whole or persistent in fruit. Corolla funnel-shaped, rarely multiple, white or variously coloured; limb shortly 5–lobed or appearing 10–lobed, folded and twisted in bud. Stamens 5, more or less equal or didynamous with two and three stamens of similar height, inserted in lower half of corolla-tube; filaments hairy at base. Anthers bilocular, basifixed, dehiscing by longitudinal slits, free or fused. Ovary 2–, or apparently 4–, locular; stigma of 2-3 elliptic surfaces at apex of style. Fruit usually a fusiform capsule, more rarely globose, 4–valved, opening regularly or irregularly from apex. Seeds flattened, corky, angular or very approximately D-shaped. Angel's Trumpets.

Brugmansia has often been confused with Datura. The two genera are easily distinguished by the long-lived, softly woody bushes reaching up to 4 m high for Brugmansia as opposed to the short-lived, summer flowering annuals of Datura. In addition Brugmansia has pendent flowers on 3-6 cm long pedicels and non spiny fruits while Datura has erect flowers on 0.5-1.5 cm long pedicels and spiny fruits (Haegi 1976).
The American Brugmansia & Datura Society maintains a comprehensive website for the two genera. However the further information provided on this site with respect to differences between the two genera as well as keys for identification of the species and images showing the internal anatomy of the flowers is no longer freely accessible. Both B. suaveolens and B. x candida are treated on this site.
B. suaveolens and B. x candida can be distinguished by the spathaceous calyx (split down one side) and recurved corolla lobes of the latter compared with the 5-toothed calyx and non-recurving corolla lobes of B. suaveolens. They are further distinguished by the fused anthers of B. suaveolens while those of B. x candida are free. B.suaveolens also has a much narrower corolla tube where it exits the calyx when compared with B. x candida. See Haegi (1976) for a table of the differences between these two species and also B. sanguinea, the other commonly cultivated species in Australia.
