All Brugmansias come from South America. They inhabit different areas, from the tropic coastal regions to the mountainous regions of the Andes.
Brugmansia arborea (L.) Lagerh. (Andes - Ecuador to northern Chile)
Brugmansia aurea Lagerh. (Andes - Colombia to Ecuador)
Brugmansia insignis (Rodr.) Lagerh. (Lower mountain zone of Eastern Peru)
Brugmansia sanguinea (Ruiz & Pav.) D.Don (Andes - Colombia to Peru and Bolivia)
Brugmansia suaveolens (Humb. & Bonpl. ex Willd.) Bercht. & J.Presl (Southeast Brazil west to Bolivia and Peru)
Brugmansia versicolor Lagerh. (Ecuador)
Brugmansia vulcanicola (A.S.Barclay) R.E.Schult. (Andes - Colombia to Ecuador)
These species are divided into two natural, genetically isolated groups. Brugmansia section Brugmansia includes the species aurea, insignis, sauveolens, and versicolor; and is causually referred to as the warm-growing group. B. section Sphaerocarpium includes the species arborea, sanguinea, and vulcanicola; and is casually referred to as the cold-growing group. All species from one group can be crossed freely to each other species in the same group. The hybrids are fertile and can be crossed with all other species within the group.
