General Description

The hardy waterlily ‘Denver’ is a free-flowering perennial cultivar with double white, cup-shaped, lightly scented flowers held above the water surface. Its petals are white but with a hint of yellow surrounding a center is filled with yellow stamens. This hybrid has green floating leaves with red-brown undersides with green veins. They are supported by flexible light green stems that arise from a thick rhizome growing hortizontally in mucky soil below.

Waterlilies require full to partial sun and sites with calm, shallow, warm freshwater. Hardy cultivars, like ‘Denver' require winter dormancy to successfully bloom and grow. Plant the rhizome directly in heavy, mucky soil or in a large submerged container filled with dense loam or clay-rich garden soil (not light potting mix). If growing waterlilies in climates with very cold winters, ensure that solid ice never reaches the submerged rhizome. In these cases plants may be better off grown in submerged watertight pots that can be pulled out and placed in a cool, dark basement to overwinter.

This is a great choice for a small tub garden or medium sized freshwater pool. It is a heavy feeder but readily produces flowers. For an elegant flower arrangement, cut waterlily blooms and float them in an attractive bowl filled with water.
