How to grow
Cultivation
Plant in a moisture-retentive, well-drained soil, best in part shade to preserve the flower colour, with the roots and base of the plant kept cool and shaded by other plants or a layer of pebbles at the base. Plant with the crown 5-8cm (2-3in) deep to encourage new shoots to grow from below ground level. Can be grown in containers at least 45cm (18in) deep and wide in a soil based potting compost. Best flower colour in part shade. See clematis cultivation for more advice
Propagation
Root softwood cuttings in spring or semi-ripe cuttings in early summer. Propagate by layering in late winter or early spring
