About

Clematis × eriostemon is a climbing member of the buttercup family Ranunculaceae that flowers from May to September. It produces woody stems that remain fragile until the plant has matured, and its opposite, divided leaves use twisting stalks to cling to support. Install a sturdy trellis, pergola or arch and train shoots in as they lengthen. Tie new growth loosely for the first several years while the stems strengthen.

About the genus

Clematis is a genus of about 380 species within the buttercup family, Ranunculaceae. Their garden hybrids and cultivars have been popular among gardeners, beginning with Clematis 'Jackmanii', a garden staple since 1862. More cultivars are being produced constantly, mainly of Chinese and Japanese origin.

In the garden

Clematis × eriostemon sits within a large genus of roughly 380 species in the Ranunculaceae. Garden clematis have been bred and selected since the 19th century, and many modern cultivars trace their parentage to Chinese and Japanese material; this hybrid belongs to that broad cultivated tradition and shares the genus’s climbing habit and floral season from May to September. Give this plant a firm framework to climb: a trellis, arch or pergola allows the leafstalks to wind and secure stems as they grow. Be aware that the woody stems can be brittle in early seasons, so avoid heavy, unsupported lengths and use soft ties to anchor new shoots. The leaves are opposite and divided, forming the typical clematis foliage that grips supports rather than twining in full stems. Where space allows, train Clematis × eriostemon up vertical structures or through larger shrubs so it can scramble and flower above other plants. Because the stems take time to develop fully woody strength, plan early-season tying and occasional adjustment rather than leaving long unsupported canes that might snap under wind or weight.
