It grows in soft dark mud under the lake surface, but its flowers and leaves stay clean and bright above the water. It has very broad round green leaves that look like small green umbrellas floating on the lake. Its pink flower petals open wide when the day is bright and full of sunshine. When cold rainy weather comes in the morning, the flower petals will close tight together to stay safe. Lots of Grade Five students love drawing water lilies in our school Art Club every week. Teachers take us to visit the lake every spring so we can watch these beautiful plants with our own eyes. Every year we draw many pictures of water lilies and stick them on our classroom wall.
