Brugmansia sanguinea alba

Originally from high up in the Andes, this is the white form of sanguinea.  Sanguineas are relatively cold hardy brugmansias, taking temperatures down to around 3C to 4C.  Flowering can actually be inhibited above 25C with late spring and autumn being the peak flowering periods.  Bring undercover before the first frosts and keep relatively dry during the winter.
