Clematis integrifolia, commonly known as the solitary clematis, is a herbaceous perennial species in the buttercup family (Ranunculaceae) native to central and eastern Europe and parts of Asia. Unlike most clematis, which are climbing vines, this species grows as an upright, non-twining subshrub, typically reaching 1 to 3 feet (30 to 90 cm) in height. It produces numerous upright or arching stems from a woody crown at the base, covered with entire (non-divided) leaves that are leathery, dark green, and slightly hairy, giving the plant a dense, bushy form. From late spring through summer, Clematis integrifolia bears nodding, bell-shaped flowers that are usually deep blue to purplish-blue, though pink or white forms also exist. Each blossom has four to six thick, slightly twisted sepals that open to reveal pale interiors and contrasting creamy stamens, creating a delicate yet striking display. After flowering, the plant develops attractive feathery seed heads that add ornamental interest well into autumn. Preferring full sun to partial shade and well-drained, moderately fertile soil, this clematis is highly valued for borders, cottage gardens, and mixed perennial plantings. It is hardy, drought-tolerant once established, and resists many common clematis diseases, making it an easy-to-grow and dependable choice for gardeners seeking color and texture without the need for climbing supports.
