It prefers high altitudes, which are drier, between to feet. Periods of frost are not uncommon there. If the cold is too severe or if it is dry for too long, the plant loses a lot of leaves along with its younger, thinner branches. Once the unfavorable environmental conditions are past, this species sends out new shoots and continues to grow.

It prefers high altitudes, which are drier, between to feet. Periods of frost are not uncommon there. If the cold is too severe or if it is dry for too long, the plant loses a lot of leaves along with its younger, thinner branches.

Once the unfavorable environmental conditions are past, this species sends out new shoots and continues to grow. They are the shortest of all the species of Brugmansia. At the edge there are clear heart-shaped indentations between the turned-back peaks, which are approximately 1 inch long. When viewed directly from below, these look like five pointed stars. During its vegetative period, B.

Unlike other species of Brugmansia that flower in bursts, its flowers develop continually. In their natural habitat the pendulous flowers are usually pollinated by moths. These are attracted both by the white color of the flowers and by the perfume that becomes stronger in the early hours of the evening. In some cases it can help to identify a plant. The corolla of B. In this species, the tube-shaped part of the corolla, which is short and narrow, is almost always covered. The calyx, covered in velvety hairs, has a deep slit on one side.

Frequently, the calyx falls off after it has been successfully pollinated. Sometimes dried bits remain stuck to the developing fruit. If the periods of frost are too long or too cold, then the plants lose their leaves and branches and freeze back into the wood. In the next vegetation period they produce new shoots without any difficulty from the surviving plant stalks.

The corolla is tube-shaped and widens out only at the mouth opening. The flower edge curves back as if it has been rolled. In this species, the length of the flower can be from 6 to 10 inches, depending on the variety. While pastel-colored corollas dominate in the other species, these plants have intense shining colors or combinations of colors. There are multicolored forms with a green flower base, yellow or cream-colored middle, and red or orange mouth found, as well as single-colored forms whose flowers are colored a brilliant red, pink, orange, golden yellow or light yellow.

No white-flowered plants have been found. The variety and the prevalent temperatures have a major effect on the coloring of individual flowers. Thus, a plant that is tricolored in summer when the temperature is about 68 degrees F, will become two-colored in fall when the temperature is about 50 degrees F. A plant that in summer has brilliant yellow flowers will have greenish yellow flowers in fall. Very warm summer months can unleash veritable explosions of color in the other species of Brugmansia, but plants of B.

This is mainly due to temperature conditions. In this species, temperatures above 71 degrees F seem to inhibit flower development. It will flower there for almost the whole winter. In their native habitat B. Hummingbirds have a well developed sense of perception within the red spectrum. Hummingbirds have a weak sense of smell. Of all the species of Brugmansia, B. References Preissel, U. Ellicott Station: Firefly Books Ltd. The corolla is tube-shaped.

Flower size is 8 — 10 inches long. The flower has yellowish green veins. Original flowers were yellow. Scent — almost none. The furry calyx is deeply slit on one side. Leaves are velvety and egg to lance shaped with the edges being dentate. Fruit are elongated and light green to yellowish in color.

An oddity of note is the tuberous formations often found in the root area. This tuberous formation tends to restrict the plant from quickly forming a dense root system.

The tubers are like roots and take up water and nutrients. Sprouts also develop on the tubers. As with B. Vulcanicola Forms Pronounced: vul-kan-ih-KOH-luh is another naturally occurring brugmansia and are the most rare of all the Angel Trumpets. They are found in Columbia in regions of high altitude and even there only isolated plants are found.

Growth habit is that of a small tree up to 14 feet tall. The calyx is split one to three times. The flowers are considered dainty. Flower life is from 5 to 8 days. Color is green at the base, red in the middle, eventually becoming yellow at the mouth. There is also a very rare pink form. The vulcanicola is considered to be difficult to grow in hot climates preferring higher altitudes with cooler climates. Vulcanicola may be crossbred with B.
