About

Nymphaea gigantea, commonly known as the giant waterlily or blue waterlily, is a perennial, herbaceous plant in the family Nymphaeaceae which is native to parts of northern and eastern Australia, and possibly New Guinea, and has been widely cultivated elsewhere. It is an aquatic plant whose natural habitat is permanent and semi-permanent still water bodies.

How to grow it

The species was brought to England by Frederick Strange, where it received notices in newspapers and began to be cultivated by nurseries.

Where it grows

The range of the giant waterlily in Australia is from northeastern New South Wales, through eastern and northern Queensland, northern parts of the Northern Territory, and the far northeast of Western Australia. Some non-authoritative sources claim it is also native to New Guinea.

Uses

Various parts of Nymphaea gigantea are edible and the plant was an important staple food for indigenous Australians across the northern parts of Australia. The golfball-sized tubers were collected from the muddy bottoms of water bodies by indigenous women and roasted before eating. The flower buds and peeled stalks were eaten raw, and the seeds could either be eaten on their own after roasting the whole fruit, or were pounded to make a flour for damper.
