isn't it patented?

I don't know the rules for propagating patented material for my own use, but I think I usually just cut and stick the hydrangea whenever I want to do it. Try it, what have you got to lose?

Endless Summer is patented, propagation prohibited. I think plant patents prohibit the sale of patented plants by unlicensed growers, not the propagation of a plant or two by a gardener.

Hydrangeas in general can be propagated all summer - the problem is overwintering a young plant if you don't get a flush of growth on it before it goes dormant. Last winter I lost several dozen hydrangeas that I had successfully rooted and planted in 4" pots. A hard freeze after weeks of mild weather was the culprit - the buds had swollen and were all killed. This year I'm overwintering the plants in my greenhouse. Good luck!
