In June, July, August and September, this Old Man's Beard's bright purple and red flowers will catch your eye as soon as you step into your cottage garden. Clematis 'Ashva' is a climbing plant that thrives in the sunlight, so is best grown up a south facing wall, fence or trellis. Once its blooms die off, the hardy shrub can be pruned ready to begin its next colourful season the following spring. Height: 2m (6'7). Spread: 1m (3'3). Pruning group 3.
