Clematis: Would a clematis do okay here?, 1 by StPaulPeg

I'm trying to spend productive time this winter planning out next year's garden. I have an area on the south side of my yard that gets a little direct sun in the morning and late afternoon, but is shaded for most of the day by tall burr oak trees. The shade is not a deep, dark shade - more dappled, with a lot of reflected light. I'm thinking of trying to grow a white flowered clematis along the fence, planting a black chokeberry (or maybe a viburnum) to the right of the oak, and then putting in a triangular mixed perennial bed in front of the shrub. I'm planning on moving the roses.

Does anyone have suggestions for a zone 4a, shade tolerant white-flowered clematis or would it be better to try another type of vine? I've also posted this in the tree and shrub forum to get some different points of view. Thanks, Peg
