B x insignis
B.x insignis is a cross between B.versicolor x B.suavolens. This hybrid occurs in nature and has developed without human influence. Its flowers clearly show the suaveolens part. It is a very thermophilic Brugmansia that only flowers well in very warm summers or in tropical areas. As a relatively high overwintering temperature (not below 12°C) is necessary, only very few specimens are kept by enthusiasts in Europe.
