Clematis is a popular perennial flowering vine found in most garden centers across the country. Available in shades across most of the color wheel, it is often used to accent homes and patios. Offer it already grown on pot trellises for the best sales appeal. Its profuse flowering habit will provide a blanket of color. Clematis grows best in a fertile, well-drained, alkaline soil. A choice site is key to the success of establishing this perennial favorite. The roots should be kept cool and moist by covering the root zone with mulch, while the vine itself should be exposed to the sun. Clematis may be planted and trained to cover walls, trellises, posts, fences, and arbors. It will need support. It is a vigorous and bushy plant that is deer resistant and resistant to walnut toxicity. Supplied as #1 grade, roots established in 2¼" pots.
Clematis Repeat Blooming (Group B)
These are early double and semi-double flowered mid-season cultivars. They bloom in mid-June and if healthy they will bloom again around September with a smaller show of color. These bloom on growth that is produced from old buds produced on stems from the previous season. If they are pruned to the ground, they will bloom, but will miss the big and beautiful early flower period. Remove dead and weak stems in February or March, leaving the best of the previous year’s buds. Once they finish blooming, cut the plant back to 16" to encourage new growth for fall flowering.
Clematis Repeat Blooming (Group C)
These are the late large-flowered clematis species. They flower in late June to August. These bloom on new wood from the current season so you do not need to maintain any old wood. They should be cut back to a living bud at about 24" from the ground in spring just as the buds swell. If you don't prune, the flowers will tend to be only up at the top of the plant and the bare stems will be unattractive below.
