General Information +

Botanical: Clematis

Common: Clematis

Family: Ranunculaceae

General Characteristics: Clematis may be planted and trained to cover walls, trellis, posts, fences, arbors or to cover rocky sites. It will need support. Prefers a rich, well-drained soil with a pH of 5.6-6.5. Clematis do best in neutral or slightly alkaline soils, but they are somewhat adaptable. If you have very acid soil, try to add some calcium when you plant. If you want to grow really good clematis you should incorporate a little lime in the planting holes. Roots should be planted in a cool moist environment, while the vine itself should be in the sun. Root area should be protected. They require 1" of water a week. 'Madame Le Coultre' is a striking clematis. Large, pure white flowers with cream stamens and broad, rounded, overlapping petals, borne from June to September. Vigorous and free-flowering. Lovely, healthy, dark green foliage.

Clematis Repeat Blooming: GROUP B: These are early double and semi-double mid-season cultivars. They bloom mid June and if healthy they will bloom again around September in a smaller show of color. These bloom on the new 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 last year's buds. Once they finish blooming, cut the plant back to 16" to encourage new growth for fall flowering.

Planting/Care Instructions +

Pests or Diseases: Deer Resistant and Resistant to Walnut Toxicity, Aphids, Clematis Borer, Stem Rot and Slugs

Planting Instructions: May be planted in any well-drained soil. Dig a hole large enough to encompass the roots without bending or circling. Set the plant in place so the crown (part of the plant where the root meets the stem) is about 1-2 inches below the soil surface. Cover with soil to the original soil surface and water thoroughly. The Clematis performs best when sufficient moisture is given and the base of the plant is kept cool. Plant in a sunny location but cover the root zone with mulch or stone. Prune the first spring after planting to 6-12" from the ground.
