Gold angels' trumpets (Brugmansia 'Charles Grimaldi') brug-MAN-see-ah Genus:  Brugmansia

Foot-long blossoms are nocturnally fragrant, and pour out from narrow calyces of light yellow, to terminate in fluted, reflexed openings the hues of golden summer squash.

Noteworthy Characteristics: 

Few plants evoke tropicalia quite like the Brugmansias , with their voluminous tubular flowers that drip from imposing shrubs or small trees. They look fantastic in containers or plunged into a border, and the dramatic display persists from late spring until autumn. All parts are highly toxic if ingested.

Care: 

Outdoors: grow in moist, well-drained soil in full sun with filtered afternoon shade. Indoors: water freely and fertilize during bloom, and keep just moist in winter. They may respond to extreme heat by dropping their leaves, but they will recuperate with cooler temperatures.  In cooler climates, Brugmansia may be brought under glass or cut back and held dormant in a cool basement.

Propagation: 

Take semi-ripe cutttings in summer; sow seed in spring.

Problems: 

Spider mites, white flies, mealybugs, caterpillars, aphids.
