Clematis Mrs Cholmondeley

Clematis ‘Mrs Cholmondeley’ is a celebrated hybrid within the large-flowered clematis family, renowned for both its spectacular visual impact and long-lasting performance. This exceptional climber has been awarded the prestigious RHS Award of Garden Merit, reflecting its consistent reliability, hardiness, and ease of cultivation. Its flowers are enormous for a clematis, with diameters of up to 20cm, providing a highly dramatic display that can completely cover walls, fences, or garden structures with elegant colour.

The petals are soft lavender-blue, catching light beautifully to create a cooling, tranquil effect across the garden. The blooms’ light brown anthers provide subtle contrast, drawing attention to the central floral structure while enhancing the overall sophistication of the plant. Blooming from late spring through to late summer, ‘Mrs Cholmondeley’ offers one of the longest flowering periods among large clematis varieties, giving a sustained display of colour that continuously refreshes the garden.

Clematis ‘Mrs Cholmondeley’ typically reaches a height of 2–3 metres, with a spread of 1–2 metres, depending on support and pruning. Its vigorous climbing habit makes it ideal for covering large walls, fences, pergolas, or obelisks, providing a dense, flowering display that creates immediate visual impact. Flowers can reach up to 20cm across, making each bloom a showstopper in its own right. This clematis also performs well in large containers, where it can be trained up obelisks or trellises to bring vertical interest to patios or terraces. With regular pruning and support, ‘Mrs Cholmondeley’ maintains a neat, manageable structure while still offering a prolific and long-lasting display of giant lavender-blue blooms.
