Flowering Months
Flowering rush requires little maintenance. The foliage can be cut back to just above water level in Autumn. When grown in an aquatic basket Butomus may stop flowering if it has insufficient space to grow. When plants become pot-bound simply lift and divide the plant in spring.
Grow Butomus in boggy soil or submerged in water to a maximum depth of 25cm (10") below water level. Choose a position in full sun.
