Clematis

Giving plenty of vigorous growth, this clematis has star-like, creamy white flowers from midsummer to mid-autumn. Give it space to spread, ideally into trees or up against a large wall where it'll need close-spaced horizontal wires or trellis to snake through. Like all clematis, it likes having its roots in the shade and its head in the sun, and being planted with the top of the roots 8cm underground. On planting, cut back to 20cm above ground, above a pair of buds. Thereafter, give an early spring prune, again 20cm above ground. It has been given the Award of Garden Merit by the RHS.
