'Denver' is a small to almost medium off-white or cream perennial waterlily. Best around 14 to 20 inches deep just be sure its below the depth of ice in winter. The pads are of interest too as it has very distinct burgundy mottling on the surface. Only needs a 10 or 12 inch pot but like all perennials the wider you pot the more room for rhizomes and more flowers. This is a perfect choice for small ponds or tub or container gardens. Fertilize monthly during the growing season with 'PondTabbs PLUS Humates' Or 'Landon Granular fertilizer' 2 times per year as it lasts 60 to 90 days per application.
