Flowers _ have a distinctive undulating margin. Additionally, the plant (21) Appl' NO" 12/584’563 has not been observed to produce any seed, and is considered (22) F 11 e d, sep 8 2009 sterile. The new cultivaris a Clematis, suitable for ornamental ' l ’ garden purposes. (51) Int. Cl.

August or September. Plants of ‘The President’ produce seed heads, which are not produced by ‘Jenmar’ due to its sterile BACKGROUND OF THE INVENTION ?owers. The new cultivar is a product of a planned breeding pro COMMERCIAL COMPARISON gram conducted by the inventor in June 2006. In 2006, the inventor, Friedrich Manfred Westphal organized a group of ‘Jenmar’ can be compared to the well known, unpatented unnamed, unpatented Clematis lanuginosa varieties to open 10 commercial variety ‘Elsa Spath.’ While ‘Jenmar’ and ‘Elsa pollinate the seed parent, the unpatented variety Clematis Spath’ are similar in most horticultural characteristics, as both patens ‘The President.’ Seeds originating from this crossing produce short plants, with a similar ?ower color, plants of were planted out, and the new variety was selected in late ‘Jenmar’ differ in having many more tepals. Additionally, 2007. All work was conducted at a commercial nursery in plants of ‘Jenmar’ are overall shorter, by approximately 20 to Pinneberg, Germany. 30 cm, and ?ower continuously all Summer, compared to During 2008 and 2009 the inventor propagated ‘Jenmar’ by plants of ‘Elsa Spath’ which consistently stop blooming dur vegetative cuttings at the commercial nursery in Pinneberg, ing the summer, then rebloom during the Fall.

Subsequent generations have shown that the ‘Jenmar’ can also be compared to Clematis ‘Dorami’ ?led unique features of this cultivar are stable and reproduced true concurrently with the USPTO, having Ser. No. 12/584,564. to type. 20 The varieties are similar in most horticultural characteristics, SUMMARY OF THE INVENTION however, plants of ‘Jenmar’ are taller, with many more tepals per ?ower than ‘Dorami.’ ‘Dorami’ typically produces ?ow ers with 6 to 8 tepals, whereas ?owers of ‘Jenmar’ have 50 to The cultivar ‘Jenmar’ has not been observed under all possible environmental conditions. The phenotype may vary 100 tepals, forming a signi?cantly different appearance to the in?orescence. somewhat with variations in environment such as tempera ture, day length, and light intensity, without, however, any variance in genotype.
