Description

Brugmansia versicolor is a bush or small tree reaching 10–16 feet in height. It has an alternate insertion of elliptic/oblong leaves that are entire with smooth edges. One of the most prominent characteristics of B. versicolor is the presence of giant drooping flowers which hang upside down, which is where it gets its common name of Angel's Trumpet. The flowers are the largest of all Brugmansia at 12–20 inches in length. They are open first white, but then may age to turn peach, pink, apricot or remain white.

Taxonomy

There are currently 7 distinct species of Brugmansia recognized, and they are very similar to their close relative Datura. For this reason the two genera were commonly mistaken for one another. “It was not until the discovery of the New World that Brugmansias appeared in the documented floras and later in gardens of the Old World. Initially Brugmansias were grouped with Daturas by the famous botanist Carl Linné, who documented them in 1753 from a drawing and not from live plant material. In 1805, the South African

 taxonomist Christiaan Hendrik Persoon created a separate genus for Brugmansia, but it was not until 1973 that Tom E. Lockwood created a final division between the two genera with his doctoral thesis at Harvard University” (Segalen).


The different genera of the family Solanaceae include many crop plants such as potatoes and tomatoes, as well as several other poisonous plants.

Distribution and habitat

Brugmansia are native to the western part of South America, originating from Guayaquil Basin and south of the Gulf of Guayaquil in Ecuador. They are usually found growing in flat areas at elevations up to 2600ft, but are also frequently cultivated at low elevations throughout the tropics.

Ecology

Brugmansia Versicolor is a hermaphrodite that reproduces perennially. It has long, narrow, fusiform berries that are up to 21 cm in length. Brugmansia reproduce by the production of seeds. The major pollinators are thought to be various species of insects, though this has yet to be proven.

Culture

Brugmansia can withstand a wide range of temperatures including those that are slightly below freezing. A moderate frost will damage the plant in colder climates. Brugmansia will grow well if placed in a partially shaded or fully lit position. The plants tend to wilt in hot temperatures, but quickily recover in the evening as their flowers begin to open. They tolerate thrive in very fertile soils and average humidity. Clones can easily be made from stem cuttings, and Brugmansia grow readily from viable seeds, however the plant will not self pollinate.

Toxicity

According to Dr. Russell, of North Carolina State University, Brugmansia versicolor is exceptionally poisonous if ingested in large quantities. It contains various alkaloids that have toxic properties which affect the mind and body. Some of these alkaloids include atropine, scopolamine, and hyoscyamine. No matter if swallowed or inhaled, the flowers, leaves, and seeds of Brugmansia will most likely cause symptoms of hallucinations, dry mouth, muscle weakness, increased blood pressure, increased pulse, fever, dilated pupils, and paralysis.
