How to Grow
Planting Clematis, including the popular ‘The President’ cultivar, is best done in spring or fall when conditions are milder. Choose a location where the vine receives full sun to part shade, understanding that the upper growth prefers brightness. Soil should be fertile, well-drained, and consistently medium in moisture. Essential to the care of all vining Clematis is providing sturdy support like a trellis immediately upon planting, as they use twining leaf stalks to climb.
Ongoing care centers on maintaining consistent moisture, especially during dry periods, as Clematis roots should never be allowed to dry out completely. A crucial cultural requirement involves keeping the root zone cool and shaded, which can be achieved by planting low-growing perennials or small shrubs at the base, accompanied by a thick layer of root mulch. Some light afternoon shade is highly beneficial in hot, humid summer climates.
Clematis ‘The President’ is classified as a Group 2 Clematis, meaning it blooms on both old and new wood. This dictates a specific pruning approach: typically, little hard pruning is needed. If you must prune heavily in fall or spring, flowering may be delayed or reduced, but not entirely prevented. Avoid disturbing the roots once established.
Landscape Uses
Clematis ‘The President’ excels when utilized vertically to maximize garden impact in limited spaces. This vine is perfectly suited for training up walls, over fences, or along arbors, injecting strong purple-blue color high above the ground layer. Its ability to provide architectural height makes it invaluable for breaking up monotonous lines in the landscape design.
Consider planting this Clematis where its lower portion can integrate with lower-growing companion plants that will naturally shade its roots, fulfilling its cultural demand for cool feet. It also performs admirably in large containers, provided the container is substantial enough to support its mature size and moisture needs are met promptly. Allow Clematis ‘The President’ to scramble through large, established shrubs for a dramatic, naturalized effect.

Companion Planting for Clematis
Selecting appropriate companion plants is essential for maximizing the health and aesthetic appeal of climbing Clematis, especially for managing the root zone of Clematis ‘The President’. Low-growing perennials that enjoy similar soil conditions—fertile, medium moisture—work best at the base. Consider planting creeping thyme, low-spreading hostas (dwarf varieties), or Geraniums around the root area. These companions effectively shade the soil, keeping the roots of your Clematis cool throughout the hot summer months as recommended.
Seasonal Care Calendar
Seasonal attention ensures your Clematis ‘The President’ remains vigorous for years of blooming. In early spring, before new growth begins, apply a slow-release fertilizer formulated for flowering plants and refresh the root mulch layer. During the active growing season (late spring through summer), monitor water needs closely; medium water should be applied consistently, focusing application at the base of the plant. Once the main flush of bloom subsides in mid-summer, some gardeners lightly cut back previous year’s stems to encourage new flower production later in the season, consistent with Group 2 pruning guidelines.
