Clematis 'Jackmanii' is a vigorous climber that will produce an abundance of large, striking, dark purple flowers from July to September. It's deciduous so will lose its foliage in autumn, and new growth will appear the following spring. It's well suited to growing in a container and can be trained to grow up a wall, fence or trellis.

Grow Clematis 'Jackmanii' in moist but well-drained soil or compost, in full sun to partial shade. Try to keep the roots cool, if they are in direct sun then provide shade with other plants, or with a cover. Clematis 'Jackmanii' is a Group 3 clematis, which means it requires regular pruning for repeat flowering because the flowers grow only on the current year's growth. Prune in late winter, when the buds are starting to emerge.
