Brugmansia is a genus of seven species of flowering plants in the family Solanaceae. They are woody trees or shrubs, with pendulous flowers, and have no spines on their fruit. Their large, fragrant flowers give them their common name of angel’s trumpetsa name sometimes used for the closely related genus Datura. Datura differ from Brugmansia in that they are herbaceous bushes, with erect rather than pendulous flowers – and most have spines on arbofea fruit. Like many ornamental plants, all parts of Brugmansia can be toxic.

They are therefore brugmwnsia as Extinct in the Wild by the IUCN Red Listalthough they are popular ornamental plants and still exist wild outside their native range as introduced species. It is suspected that their extinction in the wild is due to the extinction of some animal which previously dispersed the brufmansia.

Brugmansia are large shrubs or small trees, with semi-woody, often many-branched trunks.

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. Brugmansia are native to tropical regions of South America, along the Andes from Venezuela to northern Chile, and also in south-eastern Brazil.

Most Brugmansia are fragrant in the evenings to attract pollinating moths. 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 bruggmansia. It has been shown that these can sequester the plant’s tropane alkaloids and store them through the pupal stage on to the adult butterfly, where they are then used as a defense mechanism, making themselves less palatable to vertebrate predators.

Linnaeus first classified these plants as part of Datura with his description of Datura arborea. Then inC. Persoon transferred them into a separate genus, Brugmansianamed for Dutch naturalist Sebald Justinus Brugmans.

Lockwood settled them as separate genera, where they have stayed unchallenged since.

Brugmansia arborea – Useful Tropical Plants

Currently, there are 7 recognized species: These species are then divided into two natural, genetically isolated groups. Brugmansia section Aeborea the cold group includes the species arboreasanguineaand vulcanicola.

Two of these species were challenged by Lockwood in his doctoral thesis. This was later disproved by crossbreeding experiments done by the Preissels, published in In modern medicine, important alkaloids such as scopolaminehyoscyamineand atropinefound in Brugmansia and other related members of Solanaceae, have proven medical value for their spasmolyticanti-asthmaticanticholinergicnarcotic and anesthetic properties, although many of these alkaloids, or their equivalents, are now artificially synthesized.

Brugmansia have also traditionally been used in many South American indigenous cultures in medical preparations and as an entheogen in religious or spiritual ceremonies. Traditional external uses have included the treating of aches and pains, dermatitisorchitisarthritisrheumatismheadaches, infections, and as an anti-inflammatory. They have been used internally much more rarely due to the inherent dangers of ingestion.

Internal uses, in highly diluted preparations, and often as a portion of a larger mix, have included treatments for stomach and muscle ailments, as a decongestantto induce vomiting, to expel worms and parasites, and as a sedative.

Several South American cultures have used Brugmansia as a treatment for unruly children, that they might be admonished directly by their ancestors in the spirit world, and thereby become more compliant. Mixed with maize beer and tobacco leaves, it has been used to drug wives and slaves before they were buried alive with their dead lord. All parts of Brugmansia are potentially poisonous, with the seeds and leaves being especially dangerous. Hrugmansia hallucinogenic effects of Brugmansia were described in the journal Pathology as “terrifying rather than pleasurable”.

In in Florida, people were admitted to hospitals from ingesting Brugmansia[31] leading one municipality to prohibit the purchase, sale, or cultivation of Brugmansia plants. They even vary with the seasons and the level of hydration, so it is nearly impossible to determine a safe level of alkaloid exposure.

Brugmansia are easily grown in a brugmanaia, 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 autumnoften 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.
