The above Clematis is one of five in the Saphyra group known to me and are growing in our garden in Cambridge UK. These clematis are marketed by a group of French nurseries which are working with breeders to produce and market plants. The collective name of this Group is Sapho.

C. 'Cleminov15' SAPHYRA®NANCY
Named Nancy after the town in the horticultural area of France, it is a low growing non clinging perennial (on further observation of this plant I could only find two of the odd-pinnate leaves exhibiting any sign of clinging) reaching a maximum of 3 feet (900 mm). It commences to flower in our garden in mid May and has continued to flower to mid July. After initial flowering has ceased, I have tried two possibilities to encourage flowering later in the season.
Option 1: To cut the plant back and to give additional feed, initially high Nitrogen followed by a high Potash feed.
Option 2: To feed the plant with a high Potash fertilizer and not cut the plant back but dead head flowers as they look scruffy.
Basically, neither action has resulted in an addition to the flowering period.
The flowering is quite prolific, but flowers do not die back gracefully, hence removal of spent flowers is desirable and to date no viable seed has formed when a few flowers are allowed to remain on the plant.
The flowers are a red/purple colour close to N74A/B on the RHS chart, and maximum 4 inches (100mm) in diameter, with 4 to 6 sepals.

The plants seem to have few clinging petioles and therefore requires to be grown through a low growing shrub or tied into a supporting structure.
Typical leaf form sown on an inch (25.4mm) grid
The reverse of the flower has a distinct Red/Purple bar set in lighter pink/purple close to N74C.
