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
