Description
Brugmansia versicolor is a bush or small tree reaching 3.0–4.9 m (10–16 ft) 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 300–510 mm (12–20 in) in length. They open first white, but then may age to turn peach, pink, apricot or remain white.[2]
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 Linnaeus, 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.[3]
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 species 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 790 m (2,600 ft), but are also frequently cultivated at low elevations throughout the tropics.[2]
Ecology
Brugmansia versicolor is a hermaphrodite that reproduces
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 quickly recover in the evening as their flowers begin to open. They 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
