Clematis aren't usually known for their interesting foliage, but rather for flowers and seedheads. But here's one you might like for the foliage and contrast with flower color; Group I, to boot; will ramble happily through whatever you give it.

Clematis alpina 'Stolwijk Gold'

There are really no better or worse clematis for your location - any should work well for you, including some that are not as hardy as most of the country would hope for.

Group 1 clems tend to be almost entirely species clematis that bloom very early in the season....some even in winter. Group 1 also tends to have any of the evergreen forms which arguably can offer the best foliage interest. However, one needs to use some caution when contemplating growing an often huge evergreen vine on an evergreen tree or shrub - lots of weight and usually sunlight and moisture issues. My favorites for foliage are C. cirrhosa (ferny leaves) and C. fasiculiflora (lighter center stripe). Both are winter bloomers with smaller, nodding flowers.

Any of the Group 2 or 3 clems work well with roses. They can all be hard pruned if necessary or conversely, pruned to suit the requirements of the rose. I like picking colors that compliment or contrast well with the roses - white flowered clems with hot pink roses, blue or purple with pale pink roses, etc. Your choice :-)) Group 3's are the later blooming varieties - mid summer to well into fall. And both pruning groups contain vines that range widely in size, although hard pruning annually on 3's generally keeps even the largest of them relatively in check.

smaller flowering types that are less susceptible to "wilt" are a good choice. If you are looking for reliable evergreen, Clematis armando is a good option.
