Clematis Jackmanii is one of the most well known clematis varieties. It was introduced in 1862 and the first late large-flowered hybrid clematis available to gardeners. The violet-purple flowering vine was named after the nurseryman George Jackman. Mr Jackman created the clematis hybrid by crossing it between clematis lanuginosa, clematis viticella, and clematis × hendersonii in 1858.

The dependable and hardy Jackmanii is still grown today as one of the most popular varieties in the United States. Jackmanii Superba Clematis is a newer improved version of the original Jackmanii, and has been bred for more attractive flower petals that are a deeper purple color than the original. The flowers will change from deep purple to a lighter lavender or violet color as the flowers get older.

Jackmanii Superba vs Jackmanii

Jackmanii Superba is considered an improved version over the original. This new plant has more profuse blooms and the flowers are slightly larger as well. We recommend growing the improved Superba variety over the traditional original jackmanii clematis. Or you can grow both for a classic vine mixed with the new and improved version! 

Jackmanii Superba Clematis Care

Caring for purple clematis jackmanii is extremely easy once established. The hardest part is getting the new plants established and the roots growing strong. This plant grows rapidly and does best in full sunlight locations that get at least 6 hours of direct sunlight. Try and choose a location where the “heads in the sun, feet in the shade”. Which means, the plant does best if the vines get direct sunlight, but the base of the plant is protected by some shade throughout the day.

The plants require well draining soil and hate wet feet, which can cause root rot and the plant to die if severe enough. We also recommend adding a layer of mulch at the base of the plant to help protect the roots and retain moisture.

Clematis Jackmanii bloom time goes from early summer and will rebloom throughout the fall until the first frost. In late fall, the flowers change to small, dry seed heads with silky tails.

We recommend providing support for clematis to grow on. It can be left to sprawl as a groundcover, but that is more difficult to do and harder to keep the plant healthy. The plants will grow by twining the leaves on any nearby support like walls, trees, shrubs, mailboxes or fences. The most common support is proving a metal or wooden trellis for the plant to climb on.

Pruning Jackmanii Superba Clematis

Clematis Jackmanii are considered a group 3 clematis, which means the vine blooms on new wood, and the plants can be cut back hard in the late winter or early spring to within 6 inches of the ground. This is a fantastic way to clear out old growth and start fresh every year. The plant can climb up the old growth if you leave it, which can provide additional support if you choose not to trim the plant back.

Fertilizing Jackmanii Superba Clematis

If you choose to fertilize jackmanii, use a balanced slow release fertilizer. Apply in spring, summer and fall if you wish. Keep in mind these plants prefer neutral soil. So an easy alternative to fertilizing is by adding high quality compost around the base each year, which will help maintain a healthy balance of nutrients. You can also get the soil tested if the plant is not looking healthy, to see if what needs to be added to the soil.

Plant Shipping

Below are some factors we consider when determining when to ship the plants depending on the timing of the order.

Winter to Early Spring

We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.

Summer

If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.

Fall into Winter

We’ll ship plants out all the way up to the end of the fall planting season!

Winter

Get your order in early to reserve your plants for Spring planting!

Once your plant is shipped you’ll receive an automated email with tracking information.
