Brugmansia vulcanicola, also known as the angel's trumpet, is considered to be the rarest of the brugmansias, in large part because of the environment in which it grows. It is a striking plant with bold foliage and bolder flowers that make it worthy of consideration and appreciation by collectors of brugmansias.
Brugmansia vulcanicola is a large shrub with small, toothed leaves. During the summer and fall, the plant produces large tubular, trumpet-like flowers, between 6 and 9 inches long and around an inch wide. The flowers are ribbed from the stem downward and flair dramatically at the bottom of the flower's bell. The color of the blossom is somewhere between pink and coral. They usually last a week.
The plant comes originally from the mountain regions of Colombia and only in isolated areas there. It grows better in higher altitudes and cooler climates. The brugmansia vulcanicola is an evergreen. It is generally a slow-growing plant and can take up to 20 years to mature.
The form of the plant is that of a small tree-like shrub made up of erect stems, reaching a top height of 10 feet and spreading up to 14 feet wide. The flowers are pendulous, drooping downward from the plant. The fruit is around 5 inches long, oval shaped and wrinkled.
The plant will grow easily, if conditions are right. Brugmansia vulcanicola is not suited to warmer climates and is susceptible to frost damage. Temperatures under 80 degrees Fahrenheit with cooler nights are ideal. The plant will grow well in partial shade and with sheltered exposure. A moist, well-drained soil is best, along with plenty of humidity. The plant can be propagated from seed and cuttings.
Brugmansia vulcanicola is relatively disease free. It can be bothered by certain pests, including, red spider mites, thrips, whiteflies, scale insects and mealy bugs. It is not self fertile. It can cross with B. sanguinea, B. arborea. and B. flava.
