About
Clematis 'Blue Belle' is a vigorous vine that reaches heights of 3 to 4 meters. It features lush green foliage and produces flowers measuring 5 to 11 centimeters in diameter. Each bloom consists of four to six deep blue-violet sepals that transition to a plum-purple hue, complemented by stamens that range from greenish-white to golden yellow. This variety blooms from late summer into early autumn. Many clematis species attract bees, offering both pollen and nectar for these pollinators.
