Blooming in mid to late spring, this small-flowered clematis usually has a second flush of blooms in midsummer. The flowers are followed by very ornamental, fluffy, silvery seedheads, which remain on the plant throughout the summer, adding further interest. The foliage of toothed leaves is divided into leaflets with sharply serrated edges. This elegant clematis is a great choice as a groundcover and looks ravishing cascading over a pergola, wall or garden fence. Lovely when sprawling through large shrubs too.

  • Thrives in moist, well-drained soils, in full sun or part shade. Ideally, Clematis prefer having their 'heads in the sun and their feet in the shade'. Keep the roots cool and shaded by other plants or add a layer of pebbles or flat stones at the base.
