Clematis x jackmanii Superba

Description from White Flower Farm

And superb it is — the International Clematis Society lists it among its top 10. An improvement on the beloved C. x jackmanii, this variety is very free-flowering, producing masses of deep violet-blue flowers up to 5 inches across from mid- to late summer. A vigorous grower, ‘Superba’ can cover a trellis or shrub in a single season. Prune it back hard each year, because flowers are produced on new growth.

For beautiful colors, extravagance of blooms, and graceful habit, nothing compares with Clematis, the queen of the flowering vines. Whether used on posts or fences, clambering through shrubs and trees, or following wire frames in borders, they will enrich the landscape. Give them good soil, reasonable moisture, and shade at their roots.
