General Culture:
Easily grown in wet soils in still water in full sun to part shade. Full sun may be best, but plants will flower with as little as 3 hours of sun per day. Plant rhizomes horizontally in spring with bud end up in mud at the bottom of a pond or water garden where water is 12 to 48" deep. If planted in containers anchored in the muddy bottom, plants may be more easily moved later on if desired. Rhizomes will overwinter without difficulty as long as the water does not freeze to the bottom.
Noteworthy Characteristics:
This hardy waterlily is a sterile hybrid which is typically grown in ponds or water gardens. Rounded, greenish leaves (to 8" across) are mottled with copper. Leaves float on the water surface. From May to frost, large, cup-shaped, semi-double flowers (to 5") with upward curved canary yellow petals and a central mass of darker yellow stamens appear on or just above the water surface. Each flower blooms for about 5 days, opening in the morning and closing at night.
Problems:
No serious insect or disease problems. Leaf mining midges and aphids can be troublesome in some areas.
Uses:
Water gardens or ponds. May also be grown in large tubs or containers.
