White flowers are produced from June to September with green foliage. Planting depth 30 to 75 cm of water. Growth spread 45 to 180 cm.
Hardy Water Lilies
Surely the most beautiful of the water plants, water lilies produce lovely flowers that float on the surface of the water while the ‘lily pads’ provide hiding places for fish and all kinds of pond creatures. By shading the water the floating leaves help to reduce algae growth.
Water lilies should be placed in the deeper part of the pond, zone 4; check the information above for optimum planting depth. Gradually acclimatise young water lilies to deeper water (over 60 cm) by raising them on a block or shelf until growing vigorously.
For re-potting use Aquatic Soil that is free from impurities. Do not bury the tuber; just the roots should be buried in the soil. Angle the growing point so that it grows across the soil surface, and firm the soil down well. Top the container with Aquatic Gravel to prevent fish disturbing the soil. Do not allow the foliage to dry out, immerse in water immediately after re-potting. Water lilies are heavy feeders: add water lily fertiliser tablets when replanting, and once or twice during the growing season.
Remove decaying foliage regularly as leaves are constantly being replaced.
