The Waterlily Collection includes both hardy and tropical horticultural selections of the genus Nymphaea developed by North American breeders during the 19th, 20th, and 21st centuries. This collection achieved Plant Collections Network accreditation from the American Public Gardens Association in 2012. 

This collection fulfills heritage, display, educational, research, and germplasm preservation functions.

Plant Exploration

While our plant exploration efforts span the globe, recent intensive work alongside our partners in Tanzania was done to find Nymphaea stuhlmannii, a presumed extinct waterlily found only in a 20-square-mile area of central Tanzania. With our partners, we increased the number of known populations from one to four, and we collected specimens for study and preservation—bringing the plant back into cultivation. Back at Longwood, we’ve used conservation horticulture to learn how to germinate seeds and propagate new plants.
