About Giant waterlily
Nymphaea gigantea, or the giant water lily, is an impressive perennial aquatic plant renowned for its enormous floating flowers and large, round leaves that can reach significant diameters. Its blooms, varying in shades of white, pink, or blue, open majestically on the water's surface, creating a dazzling visual spectacle. It is ideal for large ponds or water features where its size can be fully appreciated.
Native range
Australia, specifically in the north and east of the continent.
Care tips
This plant requires full sun for optimal blooming, at least 6 hours of direct sunlight daily. It needs a calm, deep body of water, with a depth of 30 to 90 cm for its rhizomes. Use a nutrient-rich substrate specifically for aquatic plants at the bottom of the pond. A common mistake is planting it in water that is too shallow or has strong currents, which can hinder its proper development and flowering.
