Description

left, alt=Antique painting of the red ''Brugmansia sanguinea'', '' Brugmansia sanguinea'' ''Brugmansia'' are large shrubs or small trees, with semi-woody, often many-branched trunks. They can reach heights of . The leaves are alternately arranged along the stems, generally large, long and across, with an entire or coarsely toothed margin, and are often covered with fine hairs. The name "angel's trumpet" refers to the large, pendulous, trumpet-shaped flowers, long and across at the opening. They come in shades of white, yellow, pink, orange, green, or red. Most have a strong, pleasing fragrance that is most noticeable in the evening. Flowers may be single, double, or more.


Taxonomy

Linnaeus Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the ...
first classified these plants as part of ''Datura'' with his 1753 description of '' "Datura arborea"''. Then in 1805, C. H. Persoon transferred them into a separate genus, ''Brugmansia'', named for Dutch naturalist
Sebald Justinus Brugmans Sebald Justinus Brugmans (24 March 1763, Franeker – 22 July 1819, Leiden) was a Dutch botanist and physician. He was the son of naturalist Anton Brugmans (1732-1789). Brugmans studied philosophy, mathematics and physics at the Universities ...
. For another 168 years, various authors placed them back and forth between the genera of ''Brugmansia'' and ''Datura'', until in 1973, with his detailed comparison of morphological differences, T.E. Lockwood settled them as separate genera, where they have stayed unchallenged since. Currently, there are seven recognized species: These species are then divided into two natural, genetically isolated groups. ''Brugmansia'' section ''Brugmansia'' (the warm-growing group) includes the species ''aurea'', ''insignis'', ''sauveolens'', and ''versicolor''. ''Brugmansia'' section ''Sphaerocarpium'' (the cold group) includes the species ''arborea'', ''sanguinea'', and ''vulcanicola''. Two of these species were challenged by Lockwood in his 1973 doctoral thesis. First, ''Brugmansia vulcanicola'' was said to be a subspecies of ''B. sanguinea'', but this was refuted by Lockwood's former mentor, R. E. Schultes in 1977. Second, Lockwood proposed that the species ''B. insignis'' was instead a hybrid of the combination (''B. suaveolens'' x ''B. versicolor'') x ''B. suaveolens''. This was later disproved by crossbreeding experiments done by the Preissels, published in 1997.


Distribution and habitat

''Brugmansia'' are native to tropical regions of South America, along the Andes from Venezuela to northern Chile, and also in south-eastern Brazil. They are grown as ornamental container plants worldwide, and have become

in isolated tropical areas around the globe, including within North America, Africa, Australia, and Asia.


Ecology

Most ''Brugmansia'' are fragrant in the evenings to attract pollinating moths. One species lacking scent, the red-flowered '' Brugmansia sanguinea'', is pollinated by long-billed hummingbirds. ''Brugmansia'' have two main stages to their life cycle. In the initial vegetative stage the young seedling grows straight up on usually a single stalk, until it reaches its first main fork at high. It will not flower until after it has reached this fork, and then only on new growth above the fork. Cuttings taken from the lower vegetative region must also grow to a similar height before flowering, but cuttings from the upper flowering region will often flower at a very low height. One interesting example of plant/animal interaction involves the butterfly '' Placidula euryanassa'', which uses ''

'' reported the following case: A woman in her 50s presented to the emergency department with blurred vision and pupil asymmetry for 3 hours. The right pupil was dilated, while the left was normal. A detailed history revealed that she had been pruning plants in her garden, when the blurred vision started. She did not complain of any other symptom. When all tests proved normal, she was finally asked to provide a photo of her garden. ''Brugmansia suaveolens'' (angel’s trumpet) was identified in the picture. On asking specific history, she reported rubbing her right eye after touching the plant’s leaves and flowers. It shows that ''Brugmansia'' is highly toxic. Even touching the leaves and flowers can transfer sufficient amounts of active principles to the hand.


Cultivation

''Brugmansia'' are easily grown in a moist, fertile, well-drained soil, in sun to part shade, in frost-free climates. They begin to flower in mid to late spring in warm climates and continue into the fall (autumn), often continuing as late as early winter in warm conditions. In cool winters, outdoor plants need protection from frost, but the roots are hardier, and may resprout in late spring. The species from the higher elevations, in ''B''. section ''Sphaerocarpium'', prefer moderate temperatures and cool nights, and may not flower if temperatures are very hot. Most ''Brugmansia'' may be propagated easily by rooting cuttings taken from the end of a branch during the summer. Several hybrids and numerous
