Victoria amazonica
Hard · Experienced growersAbout Amazon Giant Waterlily
Victoria amazonica, the giant Amazon water lily, is the largest and most spectacular water lily in the world, native to the shallow lakes and backwaters of the Amazon River basin. Its circular floating leaves can reach an astonishing 3 meters in diameter — large enough to support the weight of a small child — with upturned rims up to 20 cm high that prevent overlap. The leaf undersides are reinforced by a remarkable network of radial ribs that inspired the design of the Crystal Palace at the 1851 Great Exhibition. The flowers are enormous, up to 40 cm across, opening white on the first evening and turning pink on the second, releasing a powerful, sweet fragrance to attract scarab beetles for pollination. It requires a large, heated pool with water temperatures above 25 degrees Celsius and is typically grown as an annual in botanical gardens outside the tropics. It remains one of the most awe-inspiring plants on Earth.

History
Victoria amazonica is native to the slow-moving backwater channels, oxbow lakes, and floodplain ponds of the Amazon basin — in Brazil, Guyana, Colombia, Peru, and Bolivia. It is the world's largest water lily, with floating circular leaves 2-3 meters in diameter, rimmed by an upright edge 5-10 cm tall, and strong enough in mature plants to support the weight of a small child (famously photographed repeatedly in Victorian and Edwardian horticultural magazines). The genus was described in 1837 and named in honor of the newly-crowned Queen Victoria. First cultivated successfully in England by Joseph Paxton, head gardener at Chatsworth House in Derbyshire, who flowered the plant in November 1849 after constructing a specially-designed heated greenhouse with steam-driven paddle wheels for water movement.
Paxton famously studied the radiating rib structure of the enormous leaves — comparing them to the ribs of a cast-iron bridge — and used the same structural principle as inspiration for the transparent glass-and-iron roof of the Crystal Palace built for the 1851 Great Exhibition in Hyde Park. The flowers bloom on two consecutive nights: the first night they open white, are warm (beetle-pollinated scarab beetles are attracted to their warmth), trap pollinator beetles overnight; on the second night they open pink-purple, release the beetles with pollen, and close permanently. Victoria amazonica caused a sensation when it was first brought to England in the 1840s.
Joseph Paxton, head gardener at Chatsworth House, was the first to coax it into bloom in cultivation in 1849 — an achievement that made national headlines. Paxton studied the ribbed structure of the leaf underside and used its engineering principles to design the Crystal Palace, the revolutionary glass-and-iron structure for the 1851 Great Exhibition in London. In the Amazon, Indigenous peoples have long collected and roasted the starchy seeds as a food source. The plant's pollination mechanism is extraordinary — flowers trap scarab beetles overnight, coating them with pollen before releasing them the next evening.
