At Wellesley, they're found in Paramecium Pond and near the shore of Lake Waban.
Water lilies can grow in water as shallow as six inches and as deep as fifteen feet.
Beneath the leaf is a hollow stem that anchors the lily to its roots at the bottom of the pond or lake. The stem brings gases from the water's surface to the rhizomes and roots, and also conveys waste gases to the surface. The flowers open and close each day for several days until they are pollinated. Once pollination occurs, the underwater stem curls like a spring and pulls the blossom underwater, presumably to protect it from damage. Claude Monet is perhaps most well known for his paintings of water lilies.
