Hello, I live up near Yonge and Finch and I was hoping to plant a climbing hydrangea along a western fence in shade, but I was unable to find any information on whether it’s possible to alter the colour of a climbing hydrangeas blooms (preferably I’d like blue if possible). Do you know if this is possible? Additionally, is it possible to grow climbing hydrangeas that have flowers closer to the snowball hydrangea rather than the lacecap? I saw pictures online of some but I’m not sure if they were Photoshopped. Many thanks!! Diana
