Clematis 'Kjell', also known as C. 'Jessica', displays large sumptuous flowers measuring 14 to 16cm (6in) in diameter. They bloom in a gradient of blue-violet with yellow-cream stamens, which stand out in contrast. It is a deciduous climbing plant that blooms twice a year, with double flowers in spring and single flowers in autumn. Of medium size and growth, it is suitable for small and large gardens, in pots or in the ground. Plant its base in a cool, shaded area with its head in the sun.
Â
The cultivar 'Kjell' is a hybrid resulting from the cross-breeding of C. Alabast 'Poulala' with C. 'Vino', obtained by S. Widberg in Sweden. It is a deciduous climber belonging to the Ranunculaceae family. Like most of its cousins, it prefers light, deep, moist, and fertile soil that is preferably neutral. It enjoys a sunny or partially shaded position, with its base always in shade. It resists cold temperatures and is not afraid of frost, even if prolonged. However, it does not tolerate stagnant humidity, so the substrate must be well-drained and watering should be moderate (if necessary, during the first year). It can be grown in a container if the pot is large enough (minimum 60cm (24in) in diameter.
Clematis 'Kjell' can reach a height of up to 2.5m (8ft) and a width of 1m (3ft). It is a Group 2 clematis, which means it has large flowers and blooms in spring, with a second flowering in late summer. The lignified stems from the previous year bear the spring flowers, which are sometimes double. The herbaceous branches from the current year bear the late summer flowering. The second wave of flowers are single stars. They are normally composed of 6 to 8 large petals. Initially purple-red, they lighten to a gradient of blue-violet with much lighter medians and red-purple markings as they approach the centre. They have a large, densely packed heart of bristly stamens. They later transform into dry fruits with persistent feathery aigrettes in winter. The deciduous and medium green leaves are composed of 3 to 5 leaflets. They are carried by voluble petioles called tendrils that wrap themselves around their support.
Plant spring bulbs and ground-cover perennials, such as white-flowering geraniums, at its base and enjoy the show with minimal maintenance. If you have a larger space, this vigorous clematis can weave through bushes or up a column, adding verticality to a colourful flower bed. Large-flowered repeat-blooming clematis are the best companions for roses. Its fairly dark flowering will be even more enhanced when paired with large shrubs with light green, variegated, and golden foliage, or up a sunny pergola with other contrasting climbers such as the cream-coloured flowers of Akebia 'Cream Form'. It will perfectly complement blue and pink schemes.

Botanical data
Plant in spring or autumn. It prefers moderately moist but not waterlogged soil that is deep, well-cultivated, drained, and rich. Plant at a depth of 5cm (2in), with the root ball placed diagonally or even lying on the ground. The head should be in the sun (or partial shade) and the base in the shade. You can place a flat tile in front of the stump or use ground cover plants to provide the necessary shade. Cover the base with a small mound of soil to encourage new shoots. After planting, cut the stems back to 30cm (12in) from the base, above a pair of buds.
Train them loosely to help the plant cling on its own.
Maintenance pruning should be done after flowering (in midsummer) to remove faded flowers and shorten the stems that have bloomed. This will help the plant to produce new shoots for a second flowering. More vigorous pruning can be done in spring to cut back certain stems more severely, but not necessarily every year.
Keep an eye out for pests such as aphids, slugs, and snails.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).

In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
