Miniature Water Lily Pots for the Patio
Nothing is more cooling in summer than a water garden filled with water lilies. Lack of space and resources for a garden pond keep most gardeners from growing these beautiful aquatic flowers, but what if a pond isn’t needed? Spacious troughs or large pots without drainage holes can be converted into small water gardens for miniature water lily varieties. If you have a partially sunny patio, deck, or flat garden space that can take the weight of a water-filled pot, you are set!
Choosing a Container
Water lily pots have to be large and spacious, so start with choosing a container that’s at least 15-18 inches deep and 24-40 inches wide. This will give you enough water-holding space for your lilies and their roots.
Pots must be water tight. Specialty “no hole” pots designed for aquascaping are sold, but you can also fill line large pots with pond liner, which is often the cheaper option. Simply cut the liner to a round that will fit in your pot and fit it snugly along the inner lip of the pot. Its helps to apply a strong, non-toxic adhesive along the edge to keep it in place.
Choosing Miniature Waterlilies
True miniature water lilies are so tiny that some even have flowers the size of a quarter. Many are pygmy waterlily (Nymphaea tetragona) variants, which are very hardy—surviving winters as cold as USDA Hardiness Zones 4-11, with good protection. They come in a suite of colors that include ivory, pale yellow, pink, and red. The best for home gardens are easy to find online or in specialty stores.
One of the tiniest miniatures is the white pygmy water lily (Nymphaea tetragona ‘Alba’). The hardy plants reach 18 to 24 inches across and sport tiny white flowers that float alongside teensie white flowers. Another beautiful white-flowered variety with much bigger, tulip-shaped flowers but a small growth habit is ‘Hermine’.
The peach-pink-flowered ‘Berit Strawn’ (Nymphaea ‘Berit Strawn’) has larger flowers (3 to 4 inches) and pads of deep green with some reddish mottling. The tiny plant is perfect for container growing, is very hardy, and will bloom nonstop from early summer to fall. Plants will spread between 24 and 30 inches.
One of the smallest red-flowered miniatures is ‘Perry Baby Red’ (Nymphaea ‘Perry Baby Red’). Its rosy red flowers compliment dark green pads. Plants spread 12 to 36 inches.
An old classic mini water lily is the hardy ‘Indiana’ (Nymphaea ‘Indiana’). Its tricolored, 2- to 3-inch flowers are in shades of rose-red, yellow, and orange. The diminutive plants have a spread of 12 to 28 inches and small green pads with reddish spots.
One of the best yellow-flowered water lilies is the cheerful ‘Yellow Pygmy’ (Nymphaea ‘Helvola’). Flowers are only a couple of inches across, but they are bright and pretty. Plants reach 18 to 36 inches across.
There are lots of great sources for miniature water lilies. Lilypons and Texas Water Lilies are good sources that offer quality selections.
Water lilies grow from fleshy tubers that must be grounded in smaller pots sunk below the surface of your water container. Choose a wide, shallow plastic pot that will fit in the bottom of your container while providing plenty of head space. Planting depth can be 5 to 24 inches from the water surface. Pots should be placed where they can get 6 hours of sun per day or more.
Line the pots with porous but tight-knit plastic burlap. The base soil should consist of a 3:1 mixture of heavy loam and Fafard Premium Natural & Organic Compost. The compost and soil must be well combined before planting. Finally, add a small amount of a slow-release, all-purpose fertilizer to the mix. Over fertilization can cause algal bloom.
Sink the tuber into the soil, so the top of the plant meets the soil line. Once it is planted, line the top 2 inches of the pot with pea gravel to help keep the soil and plant in place. Place the pot on the bottom on the container and stabilize a flat, 1 to 2 inch thick rock along one side of the pot, so it sits at an angle; this helps with gas exchange for healthy root growth. Gently fill the pot with clean tap water to a depth a couple of inches below the lip of the pot.
Maintaining Potted Waterlilies
Keeping the water clean in your water lily pot is important. Remove any debris that falls in the water, and cut old leaves from your water lilies. Refresh the water regularly as it recedes. Small- to medium-sized water pots don’t need aeration filters.
Water-filled containers cannot be allowed to freeze in winter, even if your water lily is hardy. Freezing and thawing can also cause containers to crack. The best course of action is to drain the container before the first freeze of the season, remove the lily pot (being sure to cut back the leaves), and store it in a water-filled bucket in a cool place. Water lily tubers should be divided every two to three years.
Water lily pots are colorful, impressive, and will brighten any summer garden spot. If you want the tranquil beauty of a pond without all the work and hassle, plant one this season.
