Propagation | Division. |
Cultivation | Very high moisture needs; do not let dry out between watering. Suitable for bogs and water gardens. Plant outside in early summer in a sheltered location in full sun.

When frost blackens the foliage in autumn, lift the rhizomes; over winter store frost-free in barely moist peat-free soil or leaf mold. In milder conditions, leave in the ground and cover with dry mulch. |
Pests | Leaf spots, rust and bacterial blight may occur. Aster yellows. Japanese beetles, caterpillars, slugs and snails. |
