Clematis 'Ernest Markham'

Royal Horticultural Society Award of Garden Merit

Clematis 'Ernest Markham', known for its vibrant magenta blooms, is the epitome of a fast-growing clematis, making it a standout among climbing plants. This perennial, large-flowered clematis vine captivates from midsummer to early fall with its profusion of 4- to 6-inch flowers. Each bloom, with blunt-tipped, wavy-edged, recurved petals, centers around frilly chocolate anthers, creating an eye-catching rounded shape. Ideal for new wood growth, 'Ernest Markham' matures into a lush vine, densely laden with flowers that beckon to bees, butterflies, and hummingbirds, creating a pollinator paradise.

This deciduous climber boasts a compact, twining, and trailing growth habit, adorned with bright green leaves that remain vibrant throughout the season. Reflecting the old adage—"The first year they sleep, the second year they creep, and the third year they leap"—this variety excels when trained up trellises, arbors, posts, or fences, adding a dramatic vertical element to gardens. Moreover, when paired with a climbing rose, 'Ernest Markham' forms an exquisite partnership, weaving through walls and fences with grace. This combination offers a succession of blooms, carrying the garden's vibrancy from the warmth of summer into the cool of fall.

Thriving in full sun to part shade, 'Ernest Markham' is adaptable to a range of soil types, from alkaline to acidic, including chalk, clay, and loams. It's imperative to choose a site that allows for optimal growth conditions: ample sunlight for the foliage and cool, shaded roots, ideally achieved with low-growing, evergreen shrubs or a thick layer of mulch. This clematis is celebrated for its ease of growth, cold hardiness, and resistance to deer, making it a robust addition to any garden.

As a Group 3 late-flowering variety, 'Ernest Markham' requires hard pruning in late winter to invigorate new growth and ensure a bountiful display of its magnificent blooms. This maintenance encourages the plant to reach its full potential each year, flourishing as one of the most spectacular fast-growing climbers. Whether used to adorn arbors, pergolas, or as a freestanding spectacle, this clematis brings a touch of the extraordinary to any setting.
