Clematis Diamantina 'Evipo039'

Diamantina Clematis

Clematis Diamantina 'Evipo039' is a deciduous climber celebrated for its unique double flowers that bloom repeatedly from late spring to early autumn. The blooms are large and fully double, with layers of overlapping petals in soft lavender-blue, creating a pompom-like appearance. The flowers can last up to four weeks, showcasing their vibrant color and intricate texture through the growing season.

Bred in the United Kingdom by Raymond Evison, this clematis was introduced to add long-lasting, colorful charm to vertical spaces such as trellises, walls, and arbors.

Design tip

The long summer show pairs well with plants that peak earlier, keeping one area interesting for months. Train the main stems early on a trellis or fence so the growth spreads sideways rather than bunching at the top.
