Nursery contributed plant descriptions

Clematis 'John Warren' offers stunning large white flowers with central bands and edges of carmine pink around red stamens. The tepals can be held somewhat informally with a ruffle and lilt. It will reach 8-10 feet tall and bloom from spring to fall. Pruning group B2.
It has breathtakingly large, 9-inch flowers with silvery-pink sepals and deep red stamens. The sepals have a darker pink bar. Blooms emerge in spring and summer, and will remain colorful longer in some shade.
