Hardy Water Lilies, (Nymphaea sp)

Hardy lilies are perennials and frost tolerant. These lilies are produced from rhizomes and grow horizontally. They are sweetly fragrant and bloom on, or just above the water's surface. Each blossom lasts 3 to 5 days and opens in the morning and closes late afternoon. They should be fed every two to four weeks from May1 through September 1. You will be able to enjoy these lilies year after year and they are available in pink, red, white, yellow, peach/orange, and a changeable, (starts one color and later changes to another)

Tropical Water Lilies

Tropical lilies are exotic! They evoke romance and glamour. They are very fragrant and are exquisite as cut flowers. Tropicals are treated as annuals and are frost tender. They hold their blossoms high above the water and come in vibrant colors- blue, lavender, pink, green, purple, red, white, yellow, and autumn shades. They grow from tubers and produce large leaves, some with frilly edges, some with striking mottling, all with spectacular blooms. They require 5-6 hours of direct sunlight and still water 6-18" deep over the rootstock. Fertilize freely every 2 to 4 weeks from May to September. Day bloomers open mid to late morning and close mid to late afternoon. Night bloomers open at dusk and remain open until mid to late morning the next day. Dark, cloudy days allow them to remain open later in the day. A pool containing both day and night blooming lilies can be enjoyed any hour of the day or night!

Planting and care instructions

Tropicals

Day and night bloomers should be planted in pots at least 12" in diameter. A three to five gallon size should suffice for each lily. Fill the pot half full with a rich garden soil and add 2 to 4 fertilizer tablets, then continue to fill the pot with soil to about 2 inches from the top. The rhizome should be then set upright with the roots buried gently in the soil. Make sure the top of the rhizome is not buried. Next add an inch or two of gravel or sand to prevent the soil from escaping into the water. Keep the gravel away from the rhizome or crown. The plant can be lowered into the water at a depth of about 6". As the plant grows it can be lowered further to a depth of 12". Use bricks under the pot to keep the desired height. Tropicals can not tolerate the cold, and should not be put outside until the water is at least 70F. Planting too early will cause dormancy and restrict the potential growth of the plant. the plants bloom from late spring to early fall depending on the weather.

Hardies

Hardies are planted the same way, but should be planted in early spring. They bloom from June to September depending on the weather, and become dormant during the colder months. As spring approaches, growth will begin again.

Algae

Although a certain amount of algae is normal, too much can be unsightly. Green water is often a problem in full sun and well fertilized plants. It is very effective to encourage a healthy growth of oxygenating and surface plants to help starve out the algae.  Sound familiar aquarium people? :)

Maintenance

Fertilize every two to 4 weeks during the spring and summer season. Prune old leaves and flowers. Treat for pests as needed.

Aphids

The symptoms are small pinholes surrounded by a brown halo. This bug problem can be controlled by simply washing the bugs off with a stream of water from a garden hose. Most insecticides are not recommended if you have fish.

"Sandwich man" a/k/a Cut worm a/k/a Delta Moth Larvae

The symptoms are small chunks cut from the leaf margin. Look for small whitish caterpillars sandwiched between two pieces of leaf. This moth caterpillar is the most common pest to water lilies. It is easily treated with Dipel. If the leaf is unsightly, simply remove it at the base of the stem.

Container Ponds

You do not have to have a large in ground pond to enjoy these plants. Any container that will hold water and is large enough for at least one pint size potted plant will work. People have used plastic child swimming pools, wisky barrels, tubs, troughs, and all sorts of things. Last week I found plastic 55 gallon storage bins, shaped like a trough or bath tub at Walmart for $14.  I am going to sink a couple of them in the ground, and have a couple more just sitting above ground. Small container ponds are great on a patio or balcony and even indoors in a well lit room.

Buying lilies

When looking for lilies, you can often find them now in garden stores. Common hardy lilies are sold as bare tubers by color and run $5 to $10. But there is a long list of special hybrids with unique colors, blooms, and lily pads. These are much more expensive and typically only available from specialized dealers. I will list a few here: First the two I brought in earlier this week:

Want to learn even more? Much of this information was taken from the Water Garden Plant Manual, a spiral bound book put out by the wholesaler I buy from. Many more hardy hybrids are listed, as well as Tropicals, floating plants, and marginals. This book is available for  $19.00
