Brugmansia or Angel’s Trumpet are easily grown in a moist, fertile, well-drained soil, in sun to part shade, in frost-free climates. Their large, fragrant flowers give them their common name of angel’s trumpets, a name sometimes used for the closely related genus Datura. Brugmansia are large shrubs or small trees, with semi-woody, often many-branched trunks. They begin to flower in mid to late spring in warm climates and continue into the fall, often continuing as late as early winter in warm conditions. In cool winters, outdoor plants need protection from frost, but the roots are hardier, and may resprout in late spring. They come in shades of white, yellow, pink and orange. Most have a strong, pleasing fragrance that is most noticeable in the evening. Flowers may be single, double, or more.
Brugmansia have two main stages to their life cycle. In the initial vegetative stage the young seedling grows straight up on usually a single stalk, until it reaches its first main fork. It will not flower until after it has reached this fork, and then only on new growth above the fork. Cuttings taken from the lower vegetative region must also grow to a similar height before flowering, but cuttings from the upper flowering region will often flower at a very low height.
Brugmansia grows best 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. Use a water soluble fertilizer. This is a very thirsty plant. It needs to be watered well and often. Propagation is through seeds and cuttings.
