The plant's flowering period is controlled by day length, hence its late flowering. 'Ken Aslet', the real thing, will flower in July. However, it seems to be quite rare, in part because the nursery stocks are contaminated with the fall- flowering type. The only way to get the real thing is to buy the plant in flower in mid-summer but even then it's a rather frail plant, perhaps due to virus infection. I've had starts of 'Ken Aslet' a couple of times, but in my present garden with its wintertime quagmire, it has always petered out within a very few years. -- Rodger Whitlock Victoria, British Columbia, Canada
