How to Grow and Care
In the wild the giant waterlily is a short-lived perennial, but at Kew, Royal Botanic Gardens it is raised as an annual from seed planted each January.
In summer the flowers are hand-pollinated and then placed in a bag. This enables easy collection of the resulting seed, in the autumn. The seeds must be kept moist, preferably in water, all the time. To prevent premature germination, or death, they are kept at a constant temperature of 15 °C. In order to begin germination it is sometimes necessary to nick the seed with a scalpel, after which germination occurs in ten days. In January the newly germinated seed is pricked out into a tiny pot which is kept in water. As the plant grows, potting on into larger pots is carried out until the plant occupies a one ton pot. Loam is used as a substrate, the key factors for this choice being that it does not float, it is rich in nutrients and it has the capacity to enclose the fertilizer that is contained in the ‘feed bombs’ given to the plant…. – See more at: Giant Water Lily – The Queen of the Water Lilies.
