Thanks for the commiserations, Carole and Daisy. My early morning walks can be a bit depressing when greeted by sights like this Brugmansiathat caught the full force of the cold winds. However it isn't all bad as our Solandra has taken everything the weather could throw at it, high winds (some bitingly cold), torrential rain, etc, without flinching. It has continued to flower profusely through it all.
Purely out of interest I counted the plants that were in flower at the moment (admittedly some only sparsely) and came up with over 50 varieties so, as I said, it isn't all bad news.
