Ordered and planted quite late (in May), it arrived with 2 stems of 50cm (20in) that had already started to grow. Since then (mid-June), it has reached 2m (7ft) in height and covers a width of 1m (3ft) with flowers.

Description

Clematis Jackmanii Purpurea ('Zojapur') is a particularly floriferous, vigorous, and hardy variety. It produces an avalanche of small, single, purple-violet flowers with a yellow-green centre, and petals that have a lighter, red-veined median strip. It blooms throughout summer. This is a spectacular and bright flowering clematis, which will generously and gracefully cover any support in the garden. It will also work wonders in a pot on a patio or balcony.

 

It belongs to the Ranunculaceae family and is a hybrid resulting from a cross between Clematis lanuginosa and C. viticella. It is part of the group of early large-flowered clematis. Clematis attach themselves to their support using petioles transformed into tendrils. Clematis Jackmanii Purpurea', a Dutch cultivar, is a deciduous climbing plant with a woody stump. It has rapid and remarkably vigorous growth, reaching a height of 2 to 3m (7 to 10ft), with a spread of about 1 to 1.5m (3 to 5ft). From June to September, this superb cultivar covers its foliage with magnificent, single, star-shaped flowers measuring 6 to 8cm (2 to 3in) in diameter. Its foliage almost entirely disappears under the avalanche of its velvety flowers, which are purple-violet with a lighter strip veined with red. In the centre, a beautiful yellow-green stamen heart can be admired. The abundant and bright flowering displays a sublime colour harmony.

 

Climbing clematis, especially those that bloom in summer, are easy to grow and can be displayed in countless ways. As essential and emblematic plants in English gardens, clematis undoubtedly bring a romantic, natural, and wild touch to the garden. They will be the perfect companions for non-remontant climbing or rambling roses, thanks to their long and uninterrupted flowering until autumn. They will undoubtedly be ideal plants for adorning and enhancing walls, trellises, pergolas, arches, and fences. They will also be spectacular when planted in trees and shrubs or in hedges, to accompany their flowering or bring colour to species chosen for the interest of their foliage. Clematis are also excellent candidates for container gardening on a balcony or patio. It is wise to avoid excessively hot locations, both in pots and in open ground. Clematis Jackmanii Purpurea will be stunning when planted with a climbing or rambling rose, Japanese maple, bamboo, ceanothus, hibiscus, wisteria, or Chinese lilac. Medium-height perennials will shade its base, such as epimedium, daylily, hellebore, iris, or phlox. Opting for species with light pink or white foliage or flowers will create a romantic harmony with the purple-violet flowering of this clematis.

Planting and care

Clematis Jackmanii Purpurea is a perfectly hardy and robust variety. It thrives in a sunny to partially shaded exposure, as well as in fertile, humus-rich, moist, and well-drained soil. Clematis like to climb towards the sun, with their base in the shade. It is essential that the base of its stem and its roots are shaded. For this, an inclined flat tile will provide the necessary shade. Similarly, a bushy perennial plant or a low-growing shrub in front of the clematis will also provide protection against the sun, while attractively concealing the clematis stump. When planting, take care when handling the root ball as clematis roots are quite fragile. Work the soil deeply and incorporate compost and a handful of bone meal or dried blood, a base fertiliser that will benefit the clematis' establishment. The plant should be placed in the hole at an angle, with the stem oriented towards the support it will climb on. Cover with soil and create a small mound to properly cover the base and stem, reducing the risk of wilting and promoting the growth of vigorous shoots from the stump. In the first few weeks after planting, regular but moderate watering will be necessary to keep the soil consistently moist. The main enemy of the clematis is excessive moisture, so the soil should never be waterlogged. Overly wet soil can cause the wilting of its stems and leaves, often resulting in death. After planting, prune the stems to 30cm (12in) or 40cm (16in) above a healthy pair of buds. Train the stems until the plant can grip onto the support with its voluble petioles. Mulch the clematis in February with garden compost or well-rotted manure, avoiding direct contact with the stems.

Care

Pruning instructions It blooms on the current year's branches. In February-March, before the start of the growing season, cut back all the previous year's stems to 30cm (12in) from the ground, above a pair of large buds. The clematis will then produce long and vigorous shoots from the base, heralding a beautiful flowering and forming a compact tuft. Prune short for vigorous growth!
