This Clematis is absolutely stunning for its large fully double or semi-double flowers which are produced during May and June followed by single flowers in September.
These can vary in colour from silvery-lilac-mauve, through lilac to lavender-blue or dark pinkish-lavender tinged purple or red.
Clematis 'Vyvyan Pennell' was raised by Walter Pennell of Pennell and Sons nursery and named in 1959 after his wife.
