The clematis 'Jackmanii' is one of the most popular and reliable climbing varieties, known for its large, deep velvety purple flowers, highlighted by lighter stamens. Its abundant bloom brightens the garden from mid-summer until early fall.
It develops a vigorous and well-branched vine, ideal for covering a trellis, pergola, fence, or a sunny to partially shaded wall. Like most clematis, it prefers rich, moist, well-drained soil, with its base in shade and its top in the sun.
Easy to maintain, the clematis 'Jackmanii' belongs to pruning group 3, which means it should be cut back hard in spring. It is generally unattractive to deer, an interesting advantage for rural gardens in Quebec.
