Clematis Jackmani Clematis 1 Gal

'Jackmanii' is a hybrid clematis cultivar resulting from a cross between C. lanuginosa and C. viticella. A profuse bloomer with 5-7" wide, open, four-sepaled (occasionally 5 or 6), violet-purple flowers covering this vine in mid to late summer. An old favorite which was introduced in England in the mid-1800s.

Grow in fertile, medium moisture, well-drained soils in full sun to part shade. Vining hybrids are best sited in locations where the flowering parts of the vine are in sun to part shade but the roots are shaded. Some light afternoon shade is usually beneficial in hot and humid summer climates. Clematis vines need a trellis or other support on which to grow. Roots should be kept cool, shaded and uniformly moist. Root areas may be shaded with perennials, annuals or small shrubs. A thick root mulch is appreciated. Do not allow soils to dry out.
