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.
