Bloom Time: June to September
Nymphaea nouchali is an aquatic flowering plant that grows from rhizomes or tubers rooted under the water. Leaves are oval to round, up to 9 inches (22.5 cm) long, with an open sinus at the leaf base where it attaches to the petiole (leaf stem). Leaves may spread up to 5 feet (1.5 m) from where the rhizome is rooted. Flowers, which have little fragrance, are star-shaped with 4 sepals and 10 to 16 petals, and are up to 5 inches (12.5 cm) in diameter. Although leaves float on the water surface, flowers are generally held up to 12 inches (30 cm) above water. They are usually pale blue (but can be pink or white) with pale yellow stamens and anthers.
USDA hardiness zone 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).
How to Grow and Care
Like any other perennial, each different Water Lily may have specific needs when it comes to their sunlight, soil, fertilization, water depth and pruning requirements. When shopping for Water Lilies, be sure to check the requirements of that specific plant, before you decide that you must have it! Generally, Water Lilies require a minimum of four to five hours of full sun each day to produce the most blooms. They should be planted in a large, wide pot, using a slightly acidic mixture of clay and loam with a pH of 6.1-7.0. Commercial potting mixes often contain amendments that float, so if you are using a commercial mix be sure that it is specifically for aquatic plants! Adding a few goldfish to your pond will take care of most insect pests that attack aquatic plants as well as devouring the mosquito larvae… – See more at: How to Grow and Care for Water Lilies
