The dream of angel trumpets that can be planted ...
... unfortunately has to burst. Because, first of all, the sobering news - there are definitely no hardy varieties. The magnificent nightshade plant is and remains a plant from the South American subtropics and does not tolerate frost at all. That means: moving back and forth between the garden and You will not be spared terrace and winter quarters, no matter which variety you choose.

Nevertheless, there is a relevant subdivision within the angel trumpet genus for this topic. Their area of origin extends from the mild regions on the Peruvian coast to 3000 m high areas of the Andes Mountains. The angel's trumpet varieties are therefore generally divided into the warm and cold groups according to their specific areas of origin. Depending on the area of origin, the varieties are sometimes used to more, sometimes less cold.
Let us first note:
- Angel's trumpets are generally not frost hardy, so they cannot be planted out
- With outdoor culture in summer, relocation to winter quarters in autumn is unavoidable
- however: some varieties are less sensitive to cold than others
What that means for the angel trumpet owner
The specific sensitivity to cold of the warm and cold varieties naturally have an impact on how they behave and how you can deal with them.
Cooler flowering conditions for cold varieties
The cold varieties, for example Brugmansia arborea, Brugmansia candida or Brugmansia vulcanicola, because of their higher tolerance to cold, they produce flowers even at lower temperatures emerged. On the one hand, they show their flower arrangement earlier in the summer vegetation phase. On the other hand, you can also expect another bloom in the winter quarters, provided it is sufficiently light and not necessarily colder than 10 ° C. Well, it's at least something! They are also generally more resistant to inhospitable weather conditions.
More sensitivity with warm varieties
The warm varieties, such as Brugmansia insignis, Brugmansia versicolor or Brugmansia suaveolens, generally bloom later in summer and generally do not bloom in winter quarters emerged. So you can safely overwinter them in the dark. In return, they are of course more heat-tolerant and tolerate heat phases better. However, you should not expose them to full sun.
