Thank you!
Although . . . as to why the Maxis hydrangea bush wasn't converted for Seasons -- I believe I know that. The old Maxis headquarters was in my climate zone (I say was because I don't know where it is now), in Central Coast California, and many shrubs, hydrangeas included, actually don't go dormant here. They bloom all year. Winter's actually our big growth season. We don't get much snow -- maybe two years out of three we will have flurries on a couple of days, and one year out of four or five a bit of it will stick for a few hours. Except at high elevations, where it snows almost every year, usually a couple of times and the snow lasts for a few days each time. But I've never seen a dormant hydrangea even on the top of Loma Prieta (one of the highest peaks in the Santa Cruz Mountains, which is right between where I live and where the Maxis headquarters is).
This doesn't interfere in my enjoyment of a seasonable hydrangea bush, though, because it doesn't look like a hydrangea to me in the first place -- it looks like some other delightful shrub that could very well go dormant in winter if it wants to. Thank you for thesde conversions!
