CLEMATIS: Always called the "Queen of Vines," nothing else makes the spectacular show of a clematis in full bloom. In almost all zones, these magnificent plants decorate mailboxes, trellises and porches with cascades of some of the most beautiful blooms in the flower kingdom, and they're not difficult to grow. There's no reason you can't add them to your landscape.
Commanding color of Mrs. N. Thompson demands attention - deep blue red petals with a scarlet central bar. Blooms May, June, and September. Large flowers (4-6"). Gracefully meandering over fences, trellises or through shrubbery, Clematis supply vertical interest. Every perennial garden should have at least one of these incredible vines.
