About Santa Cruz water lily
Victoria cruziana, also known as the Santa Cruz water-lily, is a stunning perennial aquatic plant renowned for its gigantic floating leaves that can reach up to 2.5 meters in diameter, featuring upturned, spiny edges. It produces large white flowers that open in the evening and turn pink by the following day. It makes a spectacular centerpiece for large ponds and ornamental water features, creating a unique visual impact.
Native range
South America, specifically in the Paraná and Paraguay river basins.
Care tips
It requires full, direct sunlight for optimal growth and warm water temperatures, ideally between 25-30°C (77-86°F). A large pond with at least 60-90 cm (2-3 feet) of water depth over the substrate is necessary to accommodate its roots and the development of its enormous leaves. The substrate should be rich in nutrients, preferably a mix of clay and organic matter; avoid light garden soil that may float. A common mistake is attempting to grow it in small or shallow ponds, which severely limits its development and flowering.
