Description Evergreen Clematis is a vigorous climbing vine that bears scented saucer shaped white blossoms in the spring.

  Morphology:
This vine is an evergreen climber in the Pacific Northwest which at maturity can attain a height of 10’ to 15’ and a width of 6’-10’. The stems of this vine twist around any support provided. Leaves are arranged in an opposite fashion and consist of 3 pinnately compound leaflets which are leathery and dark glossy green in color. Leaves are typically 2”-3” in length and 1” wide, pointed, and tend to droop downward.

In the spring white, fragrant flowers begin to form. Each flower has 4-7 sepals. Flowers can attain a width of 2.5” and are often arranged in large branched clusters.

  Adaptation:
Clematis does best in sun to partial shade where the base of the vine can be kept cool. They thrive when the soil is high in organic matter and is well drained. After the bloom has faded gardeners generally have to do extensive pruning in order to thin out the dead stems on the interior of the vine.

  Pests:
Slugs are attracted to clematis.
