We often get the question... "What is a changeable water lily?". Well, it is what it sounds like. The color of the bloom will change slightly each day the bloom is open. While most hardy water lilies will change in the depth of their color, they do not all change color. A changeable water lily is one that has a noticeable color change from the first day of the bloom to the last day. We recommend taking a picture each day of the bloom, so you can compare and see the difference!
