In the garden

Clematis 'Joan Picton' belongs to the genus Clematis within the buttercup family, Ranunculaceae, and is cultivated for its extended flowering period. As a climbing, deciduous plant it will twine up supports and perform where a sustained display from late spring into early autumn is required, with flowers appearing between May and September. Plant it where it receives full sun or partial shade; the cultivar tolerates a wide range of soils—chalk, clay, loam or sand—provided they remain moist but well drained and can be acid, neutral or alkaline. It copes with both exposed and sheltered sites and is hardy to H5, so it endures ordinary UK winter conditions when sited appropriately. Clematis 'Joan Picton' works well on vertical supports: walls, fences, obelisks and pergolas are all suitable, and it can be trained into trees or grown in containers or mixed borders to provide height and seasonal blooms. Expect a steady succession of flowers from May through September once the plant is established, making it a useful choice for extending the flowering season in a border or on a structure.
