It is closely related to Datura, belonging to the same nightshade family, solanaceae. Brugmansia blooms dangle like great trumpets or bells while Datura blooms stand erect.
When the leaves first appear their colour is red-pinkish, but then they turn deep green and grow to about 12 to 18 cm long. They are attached to long flexible stalks, which makes them rustle, flutter and dance in the slightest whiff of wind
