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.
Clematis Corona. Dark green leaves and, from late spring to midsummer, and again in early autumn, large, reddish-purple to purple-pink flowers. Early flowers are occasionally semi-double.
