This one seems to bloom whenever it wants to, but not in the hottest time of the year. We have bloomed it in the winter and spring, and it carries over into early summer. I can't recommend it for short growing seasons though, as it seems to need some plant mass before initiating flowering. So if one plants in the spring it may not be large enough to bloom before it gets warm, and then may not survive the winter. This is best a high Zone plant. We are actively hybridizing with it, so who knows what the future might bring.
