 Water lilyNymphaea species, Nymphaea cultivarsWater PlantsRequires good light, very rich soil, typically undisturbed and shallow water, though with good light and clear water some plants will grow up to 15' deep. The amount of room required varies per species and cultivar; some grow comfortably in half-barrels, 4-6" below water surface. Set rhizomes just below soil surface; leave crown bare. Divide the rootstock in spring, each section with one or two good eyes; start these close to the water surface, and lower to the final depth every few weeks Can also be propagated from seed, though may not come true to type, and takes years to grow to reasonable size. Jelly surrounds fresh seed; spread seed and jelly over heavy soil, barely covered, and set the pot itself just below water level. Keep warm, provide ample light. Repot into individual pots with first set of real leaves, then pot on as required, always setting top of seedling just below water level Some species hardy to zone 5; rhizomes should be deep enough that these cannot freeze, or can be removed from shallow ponds or container gardens before freeze-up, and overwintered in wet peat moss. Remove roots and leaves, and keep at temperatures above 32F/0C and up to 55F/12C, setting them out after the last frost Tropical species have the same requirements, but do not do well until water has warmed to some 68F/20C. May be grown as annuals in cooler climates. Start these lilies with the crown some 4" below water surface, then set deeper a month or two later; final depth depends on variety. Roots should be covered, but crown must be left bare. Hardy zone 10 only
