Clematis 'Vyvyan Pennell'

Clematis 'Vyvyan Pennell' is a remarkable viticella cultivar that thrives in full sun. In early summer, wholly double deep blue blooms form luscious pompoms. Later blooms are often single and more mauve in colour, indicating a second flush in late summer. It is ideal for creating a regal display on walls and fences, as well as training on an obelisk in borders and containers. Height: 3m (10'). Spread: 1m (3') Pruning group: 2.
