Available to ship Late March/Early April 2022. Hardy Water Lilies are perennial pond plants. A hardy water lily, will reward you with many flowers throughout the summer months. They overwinter well and the waterlily will return each spring, once again rewarding you with a lovely pond plant. Hardy water lilies provide coverage for your fish and help shade the water, which will help to control algae. We ship actively growing water lily plants. Water temperatures must be 62-65 degrees when planting in the spring so the water lilies are not shocked back into winter dormancy. All water lilies are shipped bare-root.
