Clematis × jackmanii
Encyclopedia
Clematis × jackmanii is the first of the modern hybrid large-flowered clematis
es of gardens. It is a climber
with large violet-purple blooms, still among the most familiar climbers seen in garden
s. It was produced from crosses made by the prominent nurseryman George Jackman (1837—1887), of Jackman & Sons, Woking
, Surrey, and released on the market in 1862.
The plant is crosses made in 1858 between Clematis lanuginosa
, the red form of C. viticella
and an earlier garden hybrid, Clematis × hendersonii, which the new hybrid eclipsed.
The spectacular success of jackmanii encorage Jackman & Sons to introduced a series of clematis hybrids, none of which ousted jackmanii from favour, and Jackman's monograph, The Clematis as a Garden Flower (with T. Moore, 1872), which he dedicated to H.S.H. Princess Mary, Duchess of Teck
, for the clematis was one of her favourite flowers.
Few of Jackman's early hybrids survive today, in part because they were grafted
, often on jackmanii, but the dependable, floriferous and hardy climber is "the" clematis of North American farmyard gardens in the East and the Midwest, where it is hardy to USDA Zone 4a; it is seen grown on trellis, fence, arbor, porch pillar, or lamppost, wherever the soil retains some moisture and the roots are shaded, even with a large flat rock. The plant flowers on the year's new growth, so pruning is best done in early spring, before the plant leafs out. Cut to the ground the plant can reach 3 m (10 ft) during the season; a column of bloom can be achieved by pruning out stems at varying heights, some as low as four buds, others above head height.
