Q.Climbing hydrangea vine
I’ve been researching a vine that could survive on a trellis or wall with limited sun. I thought I had found the answer with a climbing hydrangea vine BUT now I have read that I’m in a different zone! I live in Southern California zone 10. Do you think this vine could survive here? My neighbor erected an extremely ugly block wall between our houses. I feel like I’m in prison when I look our my windows on that side of my house!! I adore hydrangeas and have had hydrangea bushes that grew like crazy on that side of my house – it’s the North side of the house – the wall faces the south but is shaded most of the day by my house.

It can be done, but it won't be easy. These are suited for colder climates, and do not tolerate heat well. I have found a list of plants that will be better suited for your area.
