The herbaceous perennial varieties should be planted between mid Autumn and late Spring in ordinary soil enriched with well rotted manure. The soil should be well drained but moisture retentive. Choose a site in full sun or partial shade. On exposed sites, stake the plants with twiggy supports.

From Late Winter TO Late Winter
All species except the invasive V. cinerea and C. pectinata can be propagated by division which should occur every third year.
