A Crown Jewel of Double-Flowered Elegance

Clematis 'Diamantina' is an extraordinary variety that brings a touch of true horticultural luxury to your garden. Part of the renowned Raymond Evison collection, this award-winning climber is celebrated for its exceptionally full, double blooms that resemble intricate pom-poms. Each flower is densely packed with layers of pointed petals in a sophisticated shade of violet-blue, which can transition through hues of mauve and purple as the season progresses. Unlike many other varieties, these flowers are incredibly long-lasting, often remaining on the plant for up to four weeks.

With its neat and compact habit, 'Diamantina' is a powerhouse of floral production. It blooms profusely in early summer, often followed by a reliable second flush in late summer and early autumn. Its manageable size makes it a perfect choice for modern gardening, where space may be at a premium but high impact is still desired. The deep green, healthy foliage provides a lush canvas for the spectacular "multi-petalled" stars, making it a sophisticated addition to any vertical display.

At The Rose Press Garden, we love...

We are absolutely mesmerised by the sheer number of petals on 'Diamantina.' It’s one of those plants that feels incredibly special and "high-fashion." We love how the flowers seem to evolve in colour as they age, and because it stays quite compact, it is our top pick for anyone who wants a "flower tower" in a large pot on their terrace. It truly lives up to its name—a real diamond in the garden!
