C. montana Broughton Star 

An introduction by the Denny's of Preston, England that won the British Clematis Society's Certificate of Merit award in 1998. The semi-double 2.5"(6cm) dusky pink flowers in late spring are set off by bronze foliage making a welcome addition to the C. Montana family. Mature height 15-20' (4.5-6m)(all Montana's will have severe frost damage when minimum temperatures fall below 0 to -10F (-12 to -18C). The plants will probably survive, however, the tops will be burnt off and the plants will not bloom.) Pruning group A
