Over the last eighteen months or so, this has been slowly taking over the pot plant market. I don't know who is producing them, but they are doing it on a grand scale.
Excellent in flower, in the end I found one cheap enough to try. The plan at the moment is to leave it in the conservatory for the winter and see if it will take a touch of cold. It is possible that by winter I will have found out that it is really tender, in which case it will come indoors and look for a windowsill!
