Paniculata
Small fragrant white flowers, vigorous grower, sweet autumn clematis
August-September
10-20'
Pruning:This clematis produces flowers directly from old stems and, therefore, pruning must not be done until right after all flowering has been completed. Prune by removing all dead and weak stems. Large established plants over 15 feet tall normally are not pruned. All stems at this time should be tied into position on their trellis or other host. Also, if the plant has outgrown it's space, the correct and only time to prune to size is right after flowering. After pruning new growth will begin, this being the stems for next years flowers.

Pruning:The above varieties first flowering comes from last season's ripened stems. In early spring watch for swelling leaf buds beginning to show. Cut all dead material off above these swelling buds. Be sure all growth is tied to trellis at this time. Do not tie too tightly, so growth can begin and not hampered by tying too tight or cracking these stems.

Ville de Lyon

10-12'
Pruning:This group blooms later and from new growth. They should be pruned in February or March as new leaf buds begin to show low on the plant. All dead material above these buds should be removed at this time. Clean out any old and/or mildewed foliage too.

The best time to plant is spring, summer or early fall in a location with 5 or 6 hours of sunlight. Clematis like sun or partial shade. Shade the roots to keep the soil cool and moist but not soggy. Either plant annuals or a low growing shrub at the base of the clematis or mulch well to keep the soil and roots cool. They have long roots so loosen the soil to a depth of 2 feet and mix the soil with peat and sand. Set the plant so the crown is 1 inch below soil level.

Stake the plant and keep it well wartered. Do not let it dry out. In later years soak the plant well during dry weather once a week. Feed twice a year.

Prune back the clematis the first spring after planting to about 10-12" to give a low branching heavier flowering vine. Apply mulch for the winter dormant months.
