Marsh clematis Clematis crispa Photo/Illustration: Michelle Gervais 1 2 3 4 5 6 7 8 9 10 11 Marsh clematis (Clematis crispa) KLEM-ah-tiss KRIS-pah Genus: Clematis A deciduous climber native to the southeastern United States, Clematis crispa bears lavender-blue, bell-shaped flowers with curly edges in summer. Its blooms are not profuse, but their elegant shape makes this plant a good choice for trellises, growing through shrubs, or planting in damp areas. The flowers are slightly fragrant and are followed by attractive seedheads. It also makes an unusual cut flower. Noteworthy Characteristics: Later flowering than most other clematis, and likes moister soils. Native to the southeastern U.S. Care: Provide consistently moist soil and full sun or partial shade. Clematis like their roots to be shaded. Plant root ball 3 inches below soil surface. Prune in early spring before growth begins by cutting back all the previous years stems to a pair of strong buds, 6 to 8 inches above the ground. Propagation: Sow seed in a cold frame as soon as ripe. Divide or take cuttings in spring. Root semi-ripe cuttings in early summer. Layer in late winter or early spring. Problems: Scale insects, whiteflies, earwigs, and aphids can occur. This species is susceptible to wilt, which can be fatal. Overview Height 6 ft. to 10 ft. Spread 1 ft. to 3 ft.
