A friend of mine reported one of these flowering a week ago. I havent seen it but I think its the same thing. He said he has had it for 8 years and it has only flowered now. Did this one take a long time to bloom? Its very nice!
I have grown this from seed and it took 4 years to flower and then has flowered annually since - it is currently going over now
