Yellow pond lily is a plant species that is native to Connecticut. A native plant is one that occurs naturally in a particular habitat, ecosystem or region without human introduction. It is well adapted to that region's soil, moisture and weather conditions. Yellow or bullhead pond-lily is found in slightly acidic to basic water of lakes, slow-moving streams and pools. There is a long history of the plant's use in herbal medicine in both North America and Europe. Leaves of the yellow pond-lily may float at the surface or be submerged underwater. Leaves measure 70 to 350 mm in length and 50 to 250 mm in width. It has bright yellow, bulb-shaped flowers with six or more petals.
