Description
Easily grown in wet soil in still water in full sun to part shade. Full sun may be best, but plants will usually flower with as little as three hours of sun per day. Plant rhizomes horizontally in spring with bud end up in containers submerged in ponds or water gardens where the water is 12-48? deep. When planted in containers, plants can be more easily moved later on if desired. Rhizomes may be planted directly in the muddy bottom of a pond. Hardy water lilies will overwinter without difficulty in the St. Louis area, whether growing in ponds or in water gardens, as long as the water does not freeze to the bottom. If necessary, however, rhizomes grown in containers may easily be lifted and overwintered in a cool frost-free root cellar or garage where winter temperatures preferably remain in the 40-45 degree F. range.
