Here is a hydrangea that grows in my yard. It gets probably more sun then it would like. And it defiantly does not have enough soil. I have to water it 2-3 times a day in the summer. Despite all that, It is beautiful this year. Last year I had 4-5 blooms because my fiance cut it back in the fall with out asking if he should first! This year he left it alone and didn't pick up the trimmers. I would like to know what type it is, if anyone can help.

Also, I have a shady to spotted shady area that I would like to put a couple different fun variety's in, maybe a pink, purple, blue... I'm in zone 6. I also was wondering if these are dividable, and when the proper time to trim or how much you are supposed to take off.
