'Madame Julia Correvon' Italian Clematis blooms for a prolonged period from late June to September, producing a large quantity of 3" bright reddish wine flowers with yellow stamens. The viticella Clematis types flower on new growth, so they do well with a hard pruning in late winter to early spring. As a self-clinging vine, 'Madame Julia Correvon' does very well growing up trellises or winding up small trees or through large shrubs. The roots are happiest in cool shade and the tops prefer full sun.
