Clematis ‘Jackmanii’

Clematis ‘Jackmanii’ is a classic, vigorous deciduous climber valued for its large, rich purple flowers produced through mid to late summer. This climber requires a suitable support to establish and grow. Plant in fertile, moisture-retentive but well-drained soil with the base shaded (mulch or low planting helps keep roots cool) and the stems trained into sun or light shade. Ideal for walls, trellises and arches, it will typically reach around 3m in height with a spread of about 11.5m when mature.

This climbing plant has been trained onto a supporting frame to create a neat, well-shaped specimen that is ready for planting. As it grows, new shoots can be guided and secured to continue developing its natural shape.

To help give a clear sense of scale, the stone wall shown in our photos measures approximately 265cm in height. We also use familiar garden tools as visual references: a digging fork (110cm tall) and a hand fork (30cm tall). These are included purely as size guides to help you better judge proportions when viewing the images.
