Clematis Jackmanii

Clematis ‘Jackmanii’ is a classic and dependable flowering vine celebrated for its masses of large, velvety deep purple flowers. Blooming from midsummer into early fall, this vigorous climber creates an impressive display of rich color across trellises, fences, arbors, and other vertical supports. Its dramatic flowers and lush green foliage make it one of the most recognizable and popular clematis varieties for home landscapes.

Known for its strong growth and prolific flowering, ‘Jackmanii’ is an excellent choice for customers looking to add height, color, and cottage-garden charm without taking up much ground space. Once established, its vigorous vines return each season with an abundance of summer blooms.

Maintenance: Plant in full sun to partial shade with fertile, well-drained soil. Keep the root zone cool and shaded with mulch or surrounding low-growing plants while allowing the vines plenty of light. Water regularly during establishment and during prolonged dry periods. ‘Jackmanii’ flowers on new growth, so you can cut stems back to approximately 12–18 inches above the ground in late winter or early spring, pruning just above healthy buds to encourage vigorous flowering stems.
