Care notes
CultivationGrow in undisturbed water in full sun. Plant in baskets in loamy soil with crowns just below soil surface and covered with pea shingle. Position basket so that it is covered by 15-25cm of water; as the plants establish gradually lower the plants to a depth of 50-70cm. Feed during the growing season with aquatic fertiliser at the manufacturer's recommended rate. Lift and store in a warm greenhouse over winter. See waterlily cultivation for more advice
PruningDeadhead and remove yellow leaves regularly
PropagationPropagate by division of rhizomes or offsets in summer, place pots in shallow water until established
