Clematis 'Multi Blue'

Multi Blue Clematis

Clematis 'Multi Blue' produces large, complex blossoms that shift noticeably as they mature. Early flowers often appear densely double, formed from layered violet-blue tepals surrounding a pale, tufted center. As blooms age, the structure can open into semi-double or star-shaped forms, revealing slender inner petaloids in lavender, silvery blue, and soft mauve tones. Subtle color variation is common, with some flowers showing cooler blue shades and others deepening toward purple, creating a changing display across the season.

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.
