Angel trumpet (Brugmansia) is tropical plant native from Venezuela to Peru (USDA hardiness zones 7-b to 10). Plants have shown to be surprising hardy outdoors in zone 6-b in a protected area. This beautiful shrub, sometimes grown in a tree form, reaches heights of 6-10 feet. It is a member of the Solanaceae family (tomato, potato, petunia, nicotiana and other great garden plants).
They are highly prized for its enormous fragrant trumpet-shaped flowers, some 10 inches or more in length. The exotic flowers emit a strong lemony scent over the evening hours; they’re pollinated by moths. Flower colors range from white, orange, yellow, and pink. Some varieties exhibit variegated foliage.
If you live in a northerly area, purchase angel trumpet in early spring and grow the plant indoors to get it well-established; move it outdoors after threat of frost has ended. Plant angel trumpet in a large 12-16 inch (or more) wide container in well-drained potting soil (media). If you live in a mild temperate climate such as in the southern U.S. or California, plant directly into a garden bed in a well-drained soil and keep well mulched. You may want to place the heavy container on a dolly and roll it around to different locations of the garden.
This fast growing plant demands lots of water, but it fails when over-watered. Keep soil moist and let soil dry out between waterings. Fertilize with a water-soluble fertilizer such as Miracle-Gro®, Peters®, and Schultz®. In the summer, when plant growth is more rapid and most blooms form, feed every two weeks according to package directions. Cut back on fertilizing in fall and do not feed over winter.
In northerly areas, bring angel trumpet(s) inside as outdoor temperatures begin to drop below 40°F. If you garden where winters are mild, protect by setting poles around it and wrap with milky white plastic. You may opt to cut back entire plant to the ground and mulch heavily to protect the crown during winter.
Occasionally snip off old spent flowers, and spur new growth. A container plant can be cut to the ground for winter.
