Clematis x viorna Annabella (Zo08169 PBRaf)

The Clematis 'Annabella' is a brand new variety of clematis obtained in the Netherlands, belonging to the group of hybrids of Clematis viorna. This lovely variety produces 2m (7ft) stems adorned throughout the summer with delicate flowers, pale blue with a hint of mauve, in the shape of small inverted bells. Succeeding in its cultivation is not difficult in full sun or partial shade, in well-drained but moist soil. This adorable clematis of modest size can fit anywhere; in a bush, on a small trellis or even in a pot on the terrace. Its flowers, of excellent longevity, allow for the creation of delightful country bouquets.

The Annabella Clematis, introduced in 2016 and still little known in France, is part of a group of hybrids obtained by cross-breeding different species such as C.crispa, C.pitcheri, C. texensis and Clematis viorna. The latter is a plant native to the southern United States, not very hardy, but producing curious fleshy bell-shaped flowers for many weeks, a characteristic that it has more or less passed on to its descendants. Plants in this group, which flower on the current year's growth, should be pruned quite severely at the end of winter.

'Annabella' is a deciduous climbing plant that attaches itself to its support through the petioles of its leaves, which are capable of twining around anything within reach. An adult plant will not exceed a height of 2m (7ft) with a spread of 1m (3ft) on the ground. Its particularly long flowering period takes place from June to September. The flowers, either solitary or in small clusters, open at the terminal end and in the axils of the leaves. They are 3cm (1in) wide, composed of 4 fused sepals forming a broad tube at the base. The corolla, blue-mauve in colour and of thick substance, opens up into 4 small reflexed lips. The flowering is followed by the formation of silky helical fruits, grey-silver in colour. The deciduous foliage consists of small rather leathery leaves, entire or divided into 3 lobes, with smooth margins, of medium green colour.

Plant your clematis alongside your climbing roses or lianas to prolong the flowering of your walls and pergolas until the end of summer. Place next to pretty perennials such as geraniums, carnations, sage nemorosa, phlox, which will provide the shade it appreciates at its base. It is a rich and diverse genus, with varieties available in all colours, shapes and sizes. Take advantage of their easiness to grow to give your garden a touch of romance and bohemianism. 'Annabella' loves to weave itself through bushes like dwarf lilacs, flowering currants or Japanese quinces, and performs very well in a large pot.

Tips: Avoid excessive fertilization that stimulates foliage growth at the expense of flowers. Do not mulch the base to avoid excessive moisture that promotes wilt disease.
