Nuphar

These hardy, aquatic perennials are natives of Japan, Europe and North America. These floating plants have several popular names; they are called Spatterdock, Brandy Bottle, Yellow Pond Lily and Yellow Cow Lily. Spatterdocks produce large leaves growing 141/2" by10". With a spread of up to 8 feet, these plants are mainly used in large water gardens. The flowers, in comparison with the leaves, are rather small; they are 2 to 21/2 inches, yellow and cup shaped. The flowers never seem like they are completely open because many of the petals somewhat resemble stamens and are hidden within several of the outer petals. The blossoms last 4 or 5 days and on the first day, have a fragrance resembling brandy. The roots of Spatterdocks are long, growing up to 15 feet. These plants may be grown in water that is several feet deep.

Pot Cultivation

Fill large, heavy-duty containers with two parts rich loam and one part well-decayed cow manure. Place one aquatic tab, for every gallon, on the bottom of the pot. Fill the pot three-fourths of the way with the dampened soil mixture and mound slightly. Set the rhizome so the cut end is against the side wall, tilting it about 45� so the growing tip is even with the surface of the soil. If the rhizome has roots attached, spread them out. Fill the rest of the space with soil, patting it to decrease air pockets and ensure root contact. Make sure the growing tip isn't covered with soil. Cover with an inch of river stone, staying clear of the growing tip. The pot may then be placed in the water. It is beneficial to start it out in shallow water until it has time to become established, which is indicated by the growth of foliage.

Propagation

Spatterdocks may be increased by division or seeds may be sown in pans of soil, which are immersed in water. The resulting seedlings can be transplanted into a shallow tank or left in the pan until large enough to plant in their permanent positions.
