I've got two .....one has just lost its last flower, it was a Christmas present from last year and the other a year older, I very enthusiastically cut the old flower stem back too far and since then it's grown two lovely new leaves and most more ....I've no idea where another flower stem would come from but I live in hope......
Will try not to make the same mistake with the new one....I've read the rhs info which is very helpful, thank you Alice, so fingers crossed i might get lucky !!
