Clematis alpina Pamela Jackman (Atragene Group)

One of the first clematis to bloom in the spring, Clematis alpina ‘Pamela Jackman’ is a deciduous climber with masses of nodding, deep blue flowers, 3 in. across (7 cm), adorned with white stamens. Dangling in the wind, the flowers open from narrow, pointed buds. As their sepals unfurl, they gradually rise from bell to flat or gracefully reflexed, revealing the white inner skirt.

One of the first clematis to bloom in the spring, Clematis alpina 'Pamela Jackman' is a deciduous climber with masses of nodding, deep blue flowers, 3 in. across (7 cm), adorned with white stamens. Dangling in the wind, the flowers open from narrow, pointed buds. As their sepals unfurl, they gradually rise from bell to flat or gracefully reflexed, revealing the white inner skirt. It is a charming progression from bud to flower. Blooming from mid to late spring, and occasionally in late summer, the flowers contrast attractively with the divided lime green leaves. They are followed by very ornamental, fluffy, silvery seedheads, which remain on the plant, adding further interest. Adding sparkle to the garden, this small-flowered clematis looks ravishing cascading over a pergola, wall, or garden fence. Lovely when sprawling through large shrubs such as rhododendrons or decorating evergreen hedges.

  • Winner of the prestigious Award of Garden Merit of the Royal Horticultural Society for its noteworthy qualities.
  • Thrives in moist, well-drained soils, in full sun or part shade. Ideally, Clematis prefer having their 'heads in the sun and their feet in the shade'. Keep the roots cool and shaded by other plants or add a layer of pebbles or flat stones at the base. 
  • Hardy, this clematis can quickly grow up to 9-12 ft. long (270-360 cm).
  • This Clematis belongs to the first group of Clematis – a group including Early-flowering clematis which flower on shoots produced in the previous summer: No regular pruning is required. Just clean them up after flowering.
  • Toxic to dogs, toxic to cats, toxic to horses.
