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.
