Most Old Man's Beard plants boast impressive flowers, but Clematis 'Asao' offers unique, two-tone, pink blooms of up to 13cm (5) wide. Their petals unfurl in May, revealing contrasting, yellow stamens. Provided the hardy shrub is grown in sunlight or partial shade up a wall, on a trellis or in a patio container, it will produce a second flush of flowers in the early autumn. The plant is therefore sure to brighten up any cottage garden throughout the season. Height: 2m (6'7). Spread: 1m (3'3). Pruning group 2.
