Description and Growing Information
Flowering Period
| 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. Keep soil wet in dry weather. Benefits from a monthly application of high potassium fertilizer. 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. |
