There are many small flowered varieties (usually in the group 3 pruning category) both vining and non-vining, that will start blooming later in the spring or early summer than the large flowered types, and may continue all summer and fall in some environments. And there are also once bloomers in the fall.
For me, out here in the hot/dry country, most of them take a break in August, but pick back up again in September.
Mostly shade is tough, but there are some that do very well in part shade.
