Angel trumpet trees need daily watering and weekly feeding with a balanced fertilizer during the summer. Brugmansia are called angel trumpets because of their trumpet-like downward facing flowers. They grow best in partial shade and like their soil to be acidic to slightly alkaline sand, loam or clay.Continue Reading
The Brugmansia genus contains seven species. They have been crossbred for decades to produce hundreds of varieties in shades of white, yellow, orange, peach and red. The flowers can be single, double or triple.
Brugmansia is an evergreen perennial in U.S. Department of Agriculture zones 10b and 11 and a tender, short-lived perennial in zones 10a and lower. It can be left in the ground all winter down to zone 8 by cutting it back and mulching the trunk and roots heavily. It will emerge from the roots in the spring. Below zone 8, it should be grown in a container and brought indoors for the winter.
Do not feed brugmansia with blooming plant fertilizer. The added phosphorous will cause the leaves to yellow and drop. A standard 20-20-20 liquid fertilizer is preferable.
Propagation is usually by cuttings because seeds do not come true to the parent. Cuttings should be 6 to 8 inches long and can be rooted in water or soil.
Brugmansia contains poisonous alkaloids that cause delirium and hallucinations and can be deadly if eaten. Keep them away from pets and children.Learn more about Outdoor Plants & Flowers
