Unpack bare roots or rhizomes on arrival and plant them within a week. Until then, keep them somewhere cool and ensure the roots remain slightly moist, never wet.

Clematis 'Jackmanii', or Jackman's clematis, is a true classic, gracing gardens with its deep, velvety violet-purple blooms since the 19th century. Its large, open flowers, reaching up to 12cm across, create a stunning contrast against their backdrop of lush green foliage. The delicate greenish-cream anthers add a refined touch, making each bloom a masterpiece in itself. Flowering generously from midsummer to early autumn, Clematis 'Jackmanii' is perfect for adding a long-lasting splash of colour to trellises, fences, and pergolas. Whether climbing up an old tree or weaving through a rose bush, it never fails to impress.
Despite its regal appearance, Clematis 'Jackmanii' is delightfully low-maintenance. A simple hard prune in late winter or early spring ensures vigorous new growth and a fresh display of flowers each year. This robust climber thrives in sun or partial shade, happily scrambling up to 3 metres with ease. With its rich history and timeless appeal, Clematis 'Jackmanii' remains one of the most popular clematis varieties worldwide. Also known as Clematis × jackmanii, it proudly holds the prestigious RHS Award of Garden Merit—a well-deserved recognition for its reliability, beauty, and outstanding performance.
Clematis 'Jackmanii' is supplied as a pip with a well-developed root system, ready to thrive in your garden. You can see an example of a pip in the last image.

Remove the packaging straight away, check the compost and water thoroughly if dry. Check the plant’s hardiness before placing it outdoors. Plant into a border or permanent container within a month, choosing the position recommended for the variety. Keep the top of the root ball level with the surrounding soil, firm gently and water well.
Soak the roots in water for three to six hours immediately before planting. Keep any crown, buds or emerging shoots above the water where possible.
Pot most bare roots into 15–20cm pots filled with peat-free multipurpose compost. Large or depth-sensitive roots, including peonies, are often best planted directly into borders.
Arrange the roots naturally without bending them. Cover the roots completely, positioning the crown and buds at the depth recommended for that particular perennial.
Keep pots in a sheltered outdoor position and water whenever the compost begins to dry. Grow on until roots hold the compost together when lifted from the pot.
Plant into a suitable border or permanent container once well rooted. Add a label and water regularly throughout the first growing season while the perennial establishes.
