Ernest Markham Clematis is a classic, vigorous climber renowned for its show-stopping display of large, velvety crimson-magenta blooms that appear generously throughout summer. Growing 9 to 15 feet when trained along a support, it makes a dramatic statement on trellises, pergolas, fences, and arbors. Full sun brings out the deepest, richest color in the flowers, and regular pruning in late winter keeps the plant vigorous and blooming freely on new growth. The deciduous foliage emerges fresh green in spring and provides a clean backdrop for the richly colored flowers throughout the season. Cold hardy and Juglone tolerant, it’s a reliable, time-tested choice for the climbing garden.
