Clematis Blue Ravine

Giant 8 inch flowers

A versatile climber, Blue Ravine offers blooms in a broad range of shapes, colours and seasons. It produces huge 8 inch Lilac-blue, flowers with overlapping oval petals that have a velvety purple centre with pink highlights which contrasts nicely with the red stamens. The blooms look striking from late spring to early autumn .


In containers, up a trellis, along a wall, fence or arbor, or trained to scramble over shrubs.


Best in moist well drained soil in full sun. In the first year after planting prune back hard to approximately one foot above ground level leaving two or three healthy buds. On established plants prune back to approximately five feet in the winter or early spring before the plant starts to grow then again lightly just after flowering to encourage a second flush of flowers.

Pruning Group 2.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot at least 15cm away from the wall, fence or support. Dig compost into the base of the hole. Remove the pot and position the plant – along with its supporting cane in the hole, leaning onto the support. The top of the rootball needs to be 8cm below the level of the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Arrange and tie the stems onto the support. Water in well and keep well watered during the plant's first year. Mulch with bark chippings or stones to keep the roots cool.
