WOW! We are impressed with the bloom power of this Clematis. It is a re-bloomer that flowers first on old wood in May-June and then again on new wood from July to mid-September. The first round of flowers are 12 cm (5 in.), semi-double, blue flowers with a hint of pink at the tips of the petals. The second round of flowers are single. Grows up to 2.5 m (8 ft)..
