These are also called by the common name 'datura'. However, datura is an annual plant, while Brugmansia is a woody plant.

Design Tips

Perfect for use as a specimen plant - the flowers attract notice easily.

Angel's trumpet can be planted in a pot (plastic is preferred since this is a large plant to move) for use on a patio or indoors.

Growing Tips

The best growth for Brugmansia occurs in acidic soil, though it can tolerate alkaline well. It does not tolerate salt well and is not drought resistant.

Angel's trumpet should be fertilized at least once a week. Large plants can be fertilized 2-3 times a week. Do not use slow-release fertilizers since these will not work fast enough. Use a water soluble fertilizer.

This is a very thirsty plant. It needs to be watered well and often. If in a pot, make sure there is enough drainage so it doesn't get waterlogged. As long as the soil appears wet and there is no wilting, the plant is fine.

Propagation is through seeds and cuttings.

Maintenance/Pruning

Train a central leader when angel's trumpet is young if you would like to grow it in tree form.

The Brugmansia Growers International advises: "The best time to trim your plant is in the fall. Always keep at least 6-10 nodes on the branches above the Y for flowers the following year. {...} It is the branches that are above the Y which will produce next year's flowers."

You don't really need to prune angel's trumpet at all unless it is getting in the way, though.

Pests & Diseases

Whiteflies can be a big problem for angel's trumpet. Cabbage worms, spider mites, and aphids are also common.

Other pests that may appear include cucumber beetles (in the midwestern United States), slugs and snails, fungus gnats (inside) and mealy bugs.

Root rots can occur if watered too frequently.

Possible diseases include tobacco mosaic, tomato spotted wilt, fusarium wilt, verticillium wilt, Phytophthora, Phoma, and Botrytis.
