Water lilies are floating flowers that come in pink, red, white, blue, and yellow colors. The flowers sit on top of a wide green leaf, or pad. Underneath the surface of the water, the stem of the water lily anchors the lily pad to the bottom of the lake or pond. They are widely used in aquatic gardens, often serving as the centerpiece.
Moisten the water lily rhizome while you prepare to plant it. Water lilies dry out easily and must be kept moist.
Fill a flower pot or tray with potting soil to within an inch of the top. Insert 10 g fertilizer pellets 2 to 4 inches into the soil around the edge of the flower pot.
Dig a hole in the soil, about 3 inches deep. Insert the rhizome with the buds at the highest point.
Fill in the hole and press the soil down around the rhizome. Cover the potting soil with 1 inch of gravel.
Place the grow box into your decorative pond or aquatic garden. If the body of water is smaller than 50 square feet and 18 inches deep, add a filtration system. The rhizome will put out shoots that grow up to the surface of the water, where it will form a lily pad.
