Brugmansia

I live in the south of england and I cover my brigmansia with straw and fleece jackets and they survive but if you are in colder area they need to be somewhere frost free when the night temps start dropping below 5-6 degrees.

I have a Blackcurrant Swirl Datura which has just set its seed pods.

They will need pruning before winter storing ... even I will do so although mine will stay outside in its pot.

Daturas are not as hardy as Brugmansias and are actually short-lived plants so survival rate is low wherever they are.
