Description
Clematis 'Jackmanii Alba' brings a touch of timeless elegance to the garden, offering a delightful display of pristine white blooms throughout the season. In spring, this variety puts on an extra-special show, producing (semi-)double flowers on the previous year’s growth, adding an extra layer of texture and charm. As summer arrives, Clematis 'Jackmanii Alba' continues to impress, unfurling large, single blooms that shine against a backdrop of rich green foliage. Whether trained up a trellis, draped over an arch, or allowed to weave through shrubs, this white Jackman's clematis provides a luminous, airy presence that brightens up any outdoor space.
True to the spirit of the classic Jackmanii group, Clematis 'Jackmanii Alba' is both vigorous and floriferous, rewarding minimal effort with a generous display. Thriving in sun or partial shade, it pairs beautifully with darker-flowered varieties or climbing roses for a striking contrast. This hardy climber flourishes in well-drained soil, and with the right pruning—light after spring flowering and harder in late winter—it will return year after year with even more enthusiasm. With its graceful habit and long-lasting blooms, Clematis 'Jackmanii Alba' proves that white flowers are anything but ordinary.
Clematis 'Jackmanii Alba' is supplied as a pip with a well-developed root system, ready to thrive in your garden. You can see an example of a pip in the last image.

Soak your Clematis 'Jackmanii Alba' roots in water for 3-6 hours prior to planting.
Plant your "White Jackman's clematis" bare roots into temporary pots with a multipurpose compost in spring and grow-on in a sheltered spot outdoors.
Choose a pot which comfortably fits the bare roots. Some have a noticeable crown which should be just below the soil surface with any top growth exposed.
Plant out into borders or permanent containers in late spring or early summer once in full growth. Choose a position in sun or shade depending on the variety.
