Clematis 'Multi Blue' is a fairly vigorous deciduous climber that grows 6-8’ and produces two types of flowers. The first are double purple blooms 4-5” produced on the old wood in the late spring and early summer and second are semi-double and produced on the current season’s new wood in late summer to early fall. Grow in sun or part shade in a protected spot to prevent damage to the flowers. Multi Blue is a member of clematis pruning group 2 which does not require major pruning just the removal of dead or weak stems in the late spring. It does well in a container or on a small obelisk or trellis.
