I don't think it is that young a plant, as one previous cane looks to have flowered. I think next season I will not grow it so cool - now that I know what species it is. Maybe with a bit warmer temps, I'll get more flowers. Though IOSPE says "carrying 3 to 4 simultaneous, resupinate flowers" so I don't think 'rafts of flowers' are on the cards... My only hope is for more canes to flower!! But if that's the case, then this plant needs to get HUGE.
