A native clematis of rapid growth to 18 feet which is similar to the sweet autumn clematis but not so fragrant. It is a good plant for the wild garden with its purple autumn foliage and decorative, plumy, whitish seed-heads. Of all the species of clematis we grow, this is without a doubt the most attractive to the various insects. It is also notable as one of the only clematis to be dioecious–sexes segregated on separate plants.
