Clematis ‘Jackmanii Superba’

Large rich dark purple flowers, with either 4, 5 or 6 petals, 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 is pruned right back and so never becomes too much of a burden on the supporting plant.
