Clematis 'Jackmanii Superba'
clematis (group 3)
- Position: full sun or partial shade

Large rich dark purple flowers clothe this popular and reliable late-flowering clematis. The abundant blooms appear from mid- to late summer and look fantastic when grown up a trellis or wall. It is also a good clematis to grow through shrubs or trees as it is pruned right back and so never becomes too much of a burden on the supporting plant. - Garden care: Cut back stems to a pair of strong buds 15-20cm (6-8in) above ground level before growth begins in early spring. Mulch in late winter with garden compost or well-rotted manure but avoid the immediate crown.
