The Blue Angel’s Trumpet is an evergreen shrub from Argentina that has stunning, blue-purple, trumpet-shaped flowers. The flowers resemble miniature angel’s trumpet flowers (Brugmansia spp.) hence the common name. It is a woody shrub up to about 6 feet in height with elliptic, medium green leaves and horizontal branches. In the spring and summer, rich purple flowers are born in small clusters on the twigs. The nodding flowers are about 2 inches long and are on long, slender stalks. They open from downy, light green flower buds. The blue angel’s trumpet is a superb, rare and beautiful plant that is not often seed in cultivation but is well worth growing. In the right environment, it is an easy plant to grow.
