Description
Easily grown in average, medium to wet soils in full sun to part shade. Best performance is in acidic, saturated, moisture-retentive soils. Plants thrive in standing water (to 12? deep) where they prefer full sun. Plants grown in garden soils prefer some afternoon shade. Plants will naturalize easily by spreading rhizomes and self-seeding to form large colonies, sometimes to the point of being considered weedy and aggressive. Plants may be grown in containers that are sunk directly to the rim in water gardens. Although plants prefer constant moisture, they grow surprisingly well in average garden soils, albeit less vigorously. Soils should never be allowed to dry out. Remove seed pods before they mature to prevent any unwanted self-seeding. Seeds that mature and drop into water can float to other locations.
