Brugmansia arborea is an evergreen shrub or small tree that grows up to 23 feet (7 m) tall. Ovate leaves have coarsely toothed margins when in their best condition. The leaves, flower stalks, fruits, and especially the young shoots are covered with fine, velvety white hairs. Flowers are intensely fragrant, trumpet-shaped, nodding to sub-horizontal, white to ivory-white or cream, and up to 7 inches (17.5 cm) long. They are produced almost continuously in smaller quantities. The oval fruits are up to 2.4 inches (6 cm) long and 1.8 inches (4.5 cm) wide.

How to Grow and Care
Plant Angel's Trumpets in well-draining soil. They like plenty of water but are prone to root rot in wet locations. Use pots with drainage holes for indoor plants.
Water Angel's Trumpet thoroughly so that the soil stays moist. The leaves will wilt when the plant is thirsty. Although Angel's Trumpet tolerates drought and responds well when watered, lack of water affects future flower production. Apply a 2 inches (50 cm) layer of organic mulch around the plant's base in dry conditions. The mulch will help the soil retain moisture.
Fertilize Angel's Trumpet with a well-balanced, water-soluble fertilizer. Do not use slow-release fertilizers. Feed outdoor plants every two weeks during the growing season with a 17-17-17 fertilizer. Feed indoor plants every two weeks while the plant is in bloom with a 15-5-10 fertilizer.
