Clematis Blue Ravine produces masses of spectacular sky-blue flowers with a violet central bar in two waves over an extended flowering period from late-spring to early-autumn. The blue sepals contrast beautifully with the dark-purple anthers backed by the deep-green foliage.  The early blooms have nice, overlapping petals while the later summer flowers are more star-like with pointed petals.

Introduced by the University of British Columbia as a Botanical Garden plant it has a compact form and is ideal for planting in containers. Can be planted in a partially shaded position to prevent the blooms fading in strong sunlight.  Blue Ravine can tend to be leggy at the base and should be underplanted with smaller shrubs.

 PRUNING GROUP 2

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.
