Landscape | Excellent for flower beds and gardens. |
Propagation | Propagate by division in early spring or early autumn, or from cuttings in spring. Can also be propagated by seed, although will likely not come true. |
Cultivation | Grow in fertile, moist soil that does not become waterlogged in winter. |
Pests | Slugs and snails can be a nuisance, as well as caterpillars. Heavy or irregular feeding may cause distortion of the stems or spikes, as can quick, dramatic temperature changes in the early stages of growth. |
Notable Specimens | Royal Botanical Gardens, Burlington, Ontario, Canada. |
