Yellow Water Lily

Yellow water lilies are perennial plants that arise on flexible stalks from rhizomes (underwater stems) and large fleshy roots that can resemble bananas. Leaves are oval heart-shape, 3 - 6 inches in diameter, shiny dark green on top and reddish-purple underneath. Leaves float on the surface and are seldom emergent. Flowers are large, bright yellow, and usually stand above the water on separate stalks.
