That will be a group 1 Clematis. This means that it blooms on old wood, so pruning will not be necessary unless it gets unruly or to remove dead vines. Winter care should be taken. This is only barely hardy in your area, and some cultivars will be a little more sensitive than others. You may need to mulch extra heavily in winter, and remove the mulch in spring. I would expect some dieback each year, but this should not be too bad.
