- Description
-
Clematis integrefolia is a shrubby, non-climbing clematis with an upright, spreading habit. The long-stalked flowers are dainty, urn-shaped and nodding, with four twisted sepals that are blue with dark-purple markings and cream-colored stamens. They will bloom best in sun as the stems tend to be weaker and sprawl more when grown in part shade (and may need staking). The roots should be kept cool and mulched to retain moisture.
Problems:
There are no serious disease or insect problems. Wilt, powdery mildew, rust, fungal spots, and stem cankers may occur. It may also be subject to scale insects, whiteflies, earwigs, and aphids.
Pruning Group 3: Hard pruning recommended in early spring.
Although no reports of toxicity have been seen for this species, some if not all members of this genus are mildly poisonous. The report on toxicity given below is based on the genus Clematis. The toxic principle is dissipated by heat or by drying.
