America’s most popular Clematis! A beloved jewel, Jackmanii Clematis delights us with multitudes of 5-6″ velvety purple blossoms. The most famous Clematis of all, Jackmanii produces flowers on both old and new wood. You can expect flowers in early to midsummer, then again in late summer into fall.
Clematis Growing Tips
Most clematis prefer full sun or light shade, although there are many that prefer more shade. Clematis need cool roots that are shaded. Plant a small shrub or large perennial directly in front of it to shade roots. A thick layer of mulch will also help to keep the soil moist. This vine prefers to be grown in moist, well-drained soil.
Plant Clematis 3″ deeper than it was in the original pot. Bury the first set of entire leaves to encourage the production of strong shoots from below soil level and to discourage clematis wilt.
