Jackmanii clematis are hybrid clematis vines and the easiest clematis vine to prune, according to Ohio State University Extension. Jackmanii vines are known as late-flowering clematis because they bloom in the summer and fall. The flowers bloom on the current season’s growth, and there is no old wood to prune from the vine. Clematis vines such as sweet autumn, orange peel and Italian clematis vines are cultivars of the Jackmanii group of clematis.
