Grow in full sun or partial shade in containers (at least 45cm deep and wide) or in the ground, in cool, moisture-retentive, well-drained soil, with the crown 5-8cm deep to encourage new shoots to grow from below ground level; keep the base of the plant and the roots cool and shaded by other plants or a layer of pebbles or flat stones; for more advice, see clematis cultivation

Propagate by internodal leaf-bud semi-ripe cuttings taken from spring to late summer, or by layering from late winter to spring
