The plant grows to 2 meters and the flowers are solitary nodding bells, terminal on each shoot and 6-7 cm in diameter. The 4 sepals are 30mm long and deep blue-purple in colour. The stamens are green-yellow.
Flowering time starts in July and runs through until September. After flowering, the fluffy white seedheads make an ornamental feature lasting well into the autumn. The plant shows its charm twice each year. C. × diversifolia 'Hendersonii' has slightly perfumed flowers.
The plant needs a place in half shade or fully shade. The best place in the garden is in between garden plants in the border because it is not a "real" climber. However, this Clematis can also be used along fences and arbors.
