While considered out in the wilderness , Brugmansia ( broog - MAN - ezed - ah ) have dead thrived in gardens around the world .
These industrial plant come in a range of condition and size and are in the main considered to be small trees .
A total of 7 metal money and 3 natural variants exist , plus legion cultivar .
irrespective of the plant , all Brugmansiasare appreciate for their foliage and often massive trumpet - shape blooms .
What Are The Angel Trumpet Tree Growing Zones? Do They Grow in Other Zones?
tender group Brugmansia will grow outside in USDA hardiness zones 9 to 12 , while moth-eaten group plant will spring up in zone 7b to 12 .
If grown in container or winter indoors , Brugmansia can grow in somewhat cooler mood as long as they are institute inside before it perplex too frigid .
Warm Group vs Cold Group
The 7 metal money and 3 variants are separated into warm and cold groups based on whether they grow higher in the Andes or closer to sea stage .
As a result , the two grouping have different zone necessity and are well crossbred with other members of the same group .
Consisting of Brugmansia arborea , Brugmansia sanguinea , Brugmansia vulcanicola , and the variant Brugmansia x flava ( a natural hybrid of B. arborea and B. sanguinea ) , the cold group was aboriginal to the Andes passel and grew at gamey altitude .
As a outcome , they can be grown outdoors as modest as USDA hardiness zona 7b .
Brugmansia vulcanicola can be difficult to produce in USDA hardiness zone 11 or higher , as it is better adapted to colder mood than other specie .
Additionally , Brugmansia sanguinea is the most beautifully bleached of Brugmansia but has fuss blooming in temperatures above 71 ° level Fahrenheit , even though it will still grow in affectionate temperatures .
The warm group is so advert because it grow at much gloomy EL , with Brugmansia aurea having been the highest grower at 6,500 to 9.800 ’ feet .
The members of this chemical group are the aforementioned Brugmansia aurea , Brugmansia Insignis , Brugmansia suaveolens , Brugmansia versicolor , and the variant Brugmansia x candida ( a hybrid of B. aurea and B. versicolor ) and Brugmansia x cubensis ( a natural cross of B. x candida and B. suaveolens )
As the name entail , members of this group require warmer temperatures to last and are best implant in USDA hardiness zona 9 to 12 .
While the species and natural variate have place zone , cultivars run to be a little different , as some are bred for cooler temperature than their parent plant .
When purchasing a cultivar , be certain to fit its individual zone requisite .
Zone Rules for Container Plants
One of the expectant reward to growing saint ’s trumpets in containers is the fact that they ’ll be able to boom in stale geographical zone than normal , as they can be winter indoors .
However , there ’s an crucial rule you must keep up when grow Brugmansia in container .
Because pots are less insular than being in the ground itself , you may either deluge the pot in the ground or you will need to bring it indoors even if you ’re in a geographical zone where the industrial plant can normally originate outdoors .
The rule for knowing if you need to bring a pot Brugmansia indoors is actually quite dewy-eyed .
start out by take down the cold zona your species or cultivar of angel ’s trumpet can grow , then add two full zones .
For instance , if the coldest zone is usually 7b , your potted Brugmansia will have to be take inside unless you ’re in zona 9b or warm .
And a quick zone plant that normally tolerates 9a will postulate to be brought in unless you ’re in geographical zone 11a or affectionate .
Keeping Potted Brugmansia Outdoors for Summer

Thus a potted cold group specimen wo n’t survive temperatures below 25 ° degrees Fahrenheit outside .
Of of course , it ’s best to land the works at heart if the temperature is due to discharge below 45 ° degrees Fahrenheit for the moth-eaten group and 50 ° degrees Fahrenheit for the warm group to keep it at its healthiest .
