Evergreen Clematis for Part Shade?
I am new to growing clematis, although the house I just moved into has 2 clematis vines growing around back (yay!). I've enclosed a picture of the front of our new house. I'd like to plant evergreen clematis on either side of the front door, right next to the japonica fatsia, and train it to go up and over the front door (meeting under the rain gutter). This spot gets morning sun and some nice indirect sun. I live in SC, where it gets pretty hot in the summer, and we've got clay soil, but I plan on amending. I want something that flowers sometimes (color - prefer white) but has pretty green leaves the rest of the year, and something that produces a lot of leaves to cover that space, and someone recommended evergreen clematis. Which variety do you think would do well in the situation I described?
Thanks so much!
