Brugmansia Species
Brugmansias are beautiful, fascinating and deadly plants. According to U.S. Department of Agriculture's Germplasm Resources Information Network, there are five Brugmansia species, as well as many Brugmansia hybrids. The American Brugmansia and Datura Society recognizes seven Brugmansia species. Does this Spark an idea?

B. arborea, B. aurea, B. sanguinea, B. suaveolens, and B.versicolor species are all South American natives. The American Brugmansia and Datura Society divides these species into an Arborea group and an Aurea group. They include another species, B. vulcanicola, in the Arborea group, along with B. arborea, B. sanguinea and a hybrid, B. x flava (arborea x sanguinea). To the Aurea group, the Society adds B. insignis, to B. aurea, B. suaveolens, B.versicolor and a hybrid, B. x candida (aurea x versicolor).

According the Brugmansia and Datura Society, although Brugmansias are easy to hybridize, species in the Arborea group will not cross with species in the Aurea group.

Common Name
-
The common name for many Brugmansia species is angel trumpet. The University of Florida's Lee County Extension notes that B. arborea, B. aurea, B. insignis and B. suaveolens, as well as the hybrid B. candida, are all called angel trumpet. The close relationship between the Brugmansia and Datura genera is the reason the common name for the B. sanguinea species is tree datura, explains online resource Wayne's Word.
