A friend gave me this hydrangea in a pot at the beginning of the season. It's been sitting on Ed's back porch looking pretty. The flowers started out lavender, but over the last several months he turned the color you see in the picture. I think I want to plant it now...it shouldn't sit in that pot too much longer probably, right? I figure I need to get it in the ground while it's still warm, give it a chance to take hold before it starts getting cold. Can you give me some input/advice for where to plant it. I don't have a clue what their sun requirements are, or any other things about how best to plant them. Any input would be appreciated.
