The flowers are a rich, slightly mauve, mid-blue with a central bar paling as the bloom matures. The six to eight tepals taper to pointed tips via somewhat wavy margins. The stamens have white filaments and yellow anthers.

Pruning will help keep your clematis vines healthy.  Pruning the dense tangle of stems opens the remaining shoots to air and light which encourages healthy growth and reduces the incidence of rot and disease.

Group 2 Clematis bloom in late spring on last years growth and again in summer on the new growth.  This group require a little more care when pruning as if you cut back too heavily after the first flush you will reduce the number of flowers on show in summer.

Prune back lightly to a set of strong buds in winter and remove any dead stems and trim to tidy the plant. After the first flush of flowers in spring, remove the spent flowers to encourage new growth and a stronger second flush in summer. Feed with a good quality liquid fertiliser after pruning to encourage growth.
