What's the difference between Datura and Brugmansia?

Question

I've grown Datura metel and Datura inoxia. But the description for Brugmansia sounds like the same plant. Anyone know?

Answer 1

At one time Brugmansia plants were included in the genus Datura, but taxonomists have divided the two groups into different genera. Brugmansias are a long-lived, woody perennial, eventually reaching heights of over 20 feet in frost-free areas. They have downward to slightly outward-facing, large (6" to 24" long) trumpet-shaped blooms, in shades of white, cream, yellow, peach, orange, pink, and red and rarely set seed. In contrast, Daturas are a short-lived herbaceous perennial (they rarely live more than 3-4 years even in frost-free areas), are usually grown as an annual, and rarely exceed heights over 6 feet. Their smaller (2" to 8" long) white, cream, yellow, lavender or purple flowers are held upright above the plants and set seed freely.

Datura fruiits are prickly but Brugmansia fruits are not.

Answer 2

Datura Brugmansia

Answer 3

Both Datura and Brugmansia are also called Angel's Trumpet. Datura is a bush growing 4 - 6 ft. Brugmansia is a tree growing up to around 15 feet.
