Brugmansia for your Garden
Commonly known as Angel Trumpets, Brugmansia are from high altitude, moist tropical cloud forests with specific temperature and humidity. These conditions vary between species but generally speaking a warm day at about 23°C combined with a high humidity will keep them happy. If night temperatures are around 10°C, give or take 3°C, a strong growth rate will ensue. In summer months these temperatures can be easily exceeded, but an average humidity of 70% will ensure optimal growth and full flower colour. The good news is, the UK has the perfect humidity and temperature to support Brugmansia growth, but the more challenging part is overwintering the plant when temperatures dip below freezing, understanding Brugmansia species is key to healthy plants.
There are seven Brugmansia species. These species are then divided into two natural genetically isolated groups, cold growing (CG) and warm growing (WG).
Cold growing Brugmansia include B. sanguinea, B. vulcanicola, B. arborea and all cultivated hybrid varieties of these are adapted to the cool climate of their native habitat in the Andes, South America.
Warm growing species include B. suaveolens, B. insignis, B. versicolor, B. aurea, and hybrid cultivated varieties of these, which all grow well in a UK summer. Each species has slightly different growing conditions.
All warm growing species originate from high humidity warm regions but frosts are unlikely due to the shelter of the rainforest, cloud forest and altitude. In their native habitat these warm growing species require a lot of water and we recommend frequently watering during the hot summer months and regularly feeding to encourage flowers.
It is important to know the microclimate of your garden balancing humidity with sun, wind and shade. Best conditions for warm growing Brugmansia species generally tend to be part shade in summer to stop the root ball drying out and over scorching the leaves or flowers. An enclosed area of your garden with some shade facing south or west will suit best, protecting them from strong winds and hot sunny days.
In the UK during prolonged cold conditions it is necessary to force Brugmansia into dormancy for the winter, during cold frosts and snow. This is easily achievable by fleecing and storing them in a dry storage room, garage, shed or greenhouse which is frost free and ventilated. The foliage can be removed but this may drop by itself which is perfectly fine. Growth will recommence again when temperatures exceed 8 to 10C.
