Such a position is required by most of the double-flowered cultivars like 'Duchess of Edinburgh', 'Kiri Te Kanawa', 'Matka Siedliska', 'Veronica's Choice' and 'Vyvyan Pennell'. Many clematis can grow well and bloom in semi-shaded places or against a wall facing north (e.g. pastel colored Clematis such as 'Comtesse de Bouchaud', 'Błękitny Anioł' and some small-flowered species - Clematis alpina and Clematis macropetala).
over fences and walls
Traning clematis to grow up various kinds of fences or walls is very popular.
over garden supports
Clematis can be grown over various kinds of garden architecture such as arbors, arches or trellises, pergolas, or simply over rods and poles.
over natural supports
Clematis feel at home when growing over perennials, or scrambling through trees, bushes or dwarf shrubs.
