Clematis 'Constance' is a deciduous, alpine clematis admired for its semi-double, deep purplish-red, bell-shaped flowers, which bloom abundantly in late spring, often with a second, smaller flush in summer. The blooms give way to fluffy, ornamental seedheads that add visual interest through summer, while the mid-green leaves, divided into 3 leaflets with serrated leaf margins, provide a fresh, natural backdrop.

This particularly free-flowering, RHS award-winning cultivar is well-suited for covering a north- or east-facing wall, making it a versatile choice for gardens needing colour and texture in shadier spots. Thriving in full sun or partial shade with well-drained soil, ‘Constance’ brings a unique charm and reliable flowering habit to any garden.
