I've had two of these plants for a great number of years. This year I decided to split one as it was getting quite big. It made six new plants. I kept 3 in the house and 3 in the unheated greenhouse all over the last winter. I didn't expect the ones in the GH to do anything as they are native to warmer climes. Suprise...........they all survived and now look happier than the pampered ones. They are showing much better signs of producing flower clusters too. Funny old world innit?
