| Maintenance | When pruning group 3 or C plants, be firm and cut back to a height of about 8"-12", including two strong sets of buds. This encourages vigorous new shoots to emerge from the base and promote a complete, multi-stemmed plant with plenty of flowers. You'll need to spread the shoots out to maximize the display as they grow. Sometimes, the plants will naturally train themselves, but most often, they will need some guidance.

| Author's Notes | Virgin's Bower (Clematis virginiana) is a native, noninvasive plant frequently mistaken for the invasive Sweet Autumn Clematis (Clematis terniflora). Although they are similar, they can be distinguished by examining the leaves. Virgin's Bower has serrated leaves, while Sweet Autumn Clematis has smooth, entire leaves. Clematis virginiana (Virgin's-bower): I have seen old plants that have taken over and collapsed supporting structures. |
