Plants of Home and Garden, Water Plants

May start from seed, surface sow, 70F/21C. Keep moist; needs light to germinate. Grow in good indirect light, water well during growing season, until finished flowering. Grown as a marginal in warmer areas, and is quite happy with 6" water overhead. Well-draining, rich soil. Zone 7-10; needs winter protection in zone 7, but can be left in place. Propagate also by offsets when replanting

Set rhizomes 4" deep, 1' apart, rich soil. Plant shallower in 6" pots, but if possible set deep into large containers. Let plant die back in fall, and dig roots after first frost, removing stems just above base. Store in a cool, slightly damp and dark place, checking every few weeks over winter. Or keep rhizomes dry and potted over winter, until growth resumes, or keep watering to keep in growth, if indoors
