What is Clematis Jackmanii?

Clematis Jackmanii, often simply called Jackman’s clematis, is a deciduous climbing vine known for its:

• Large, deep purple flowers (4-6 inches across)
• Vigorous growth (can reach 10-12 feet in height)
• Long blooming period (typically June to September)
• Ability to thrive in various climates (USDA zones 4-8)

First introduced in 1862 by English nurseryman George Jackman, this hybrid clematis quickly became popular due to its stunning flowers and robust nature.

How to Plant Clematis Jackmanii

Choosing the Right Location

Clematis Jackmanii thrives in:

• Full sun to partial shade (at least 6 hours of sunlight daily)
• Well-draining soil rich in organic matter
• Areas with good air circulation

Remember the old gardener’s saying: “Clematis like their heads in the sun and their feet in the shade.” This means the vine prefers cool, moist roots and sunny foliage.

Planting Steps:

1. Dig a hole twice the size of the root ball.
2. Mix compost or well-rotted manure into the soil.
3. Plant the clematis 2-3 inches deeper than it was in its nursery pot.
4. Backfill with soil and water thoroughly.
5. Mulch around the base to keep roots cool and moist.

Caring for Your Clematis Jackmanii

Watering

• Water deeply and regularly, especially during the first growing season.
• Aim to keep the soil consistently moist but not waterlogged.

Fertilizing

• Feed your clematis in early spring with a balanced, slow-release fertilizer.
• Apply a layer of compost or well-rotted manure around the base annually.

Support

Clematis Jackmanii needs sturdy support to climb. Options include:

• Trellises
• Arbors
• Fences
• Sturdy garden structures

Ensure the support is in place at planting time to avoid disturbing the roots later.

Pruning

Clematis Jackmanii belongs to pruning Group 3, which means it blooms on new wood. Here’s how to prune:

1. In late winter or early spring, cut all stems back to about 12-18 inches from the ground.
2. Remove any dead or weak growth.
3. Throughout the growing season, you can trim lightly to shape the plant if needed.

This pruning method encourages vigorous new growth and abundant blooms.
