Description

Nymphaea tetragona, also known as White Water Lily, is the smallest of water lilies, making it perfect for small ponds, containers, and barrels on the terrace. It bears semi-double star-shaped, white flowers with yellow-orange stamens, 5 to 8 cm (2 to 3in) in diameter. The dark olive green leaves with purple spots are also precious. A jewel to admire up close.

 

The dwarf white water lily belongs to the Nymphaeceae family, and its distribution range covers a large part of the Northern Hemisphere: northern Europe (Finland, western Russia), temperate to tropical Asia (India, China, Japan, Kashmir, Kazakhstan, Korea, Vietnam) and northern North America (northwestern United States, Alaska, central and western Canada). It is grows abundantly in calm waters (lakes, ponds, pools, marshes, streams) at shallow depths. It is a perennial aquatic plant with a vertical, unbranched, non-stoloniferous rhizome. The floating leaves are oval to elliptical (length: 3-13 cm (1-5in), width: 2-11 cm (1-4in)), with a purplish underside, heart-shaped at the base, with parallel basal lobes, entire margins, and smooth petioles. The solitary and floating flowers, with a diameter of 3 to 8 cm (1 to 3in), open during the day and are sometimes fragrant. They consist of 4 green, oval to lanceolate sepals, 2 to 3.5 cm (1in) long, with 10-17, lanceolate to oblong, white petals and 30 to 70 yellow-orange stamens. Flowering is followed by fruits containing numerous seeds which ripen underwater and release floating seeds that will eventually sink and germinate in the mud.

 

Choose easy and floriferous varieties that are proportionate to your pond. With their spectacular and diverse flowers, Water Lilies will be the main attraction in your pond. Most of them bloom from spring until early autumn. Water lilies are essential for maintaining a balanced garden pond, as they contribute to the oxygenation of the water. Their leaves will provide shade and shelter for your fish, who, in return, will protect them from predatory insects such as aphids.

 

The genus name comes from the Greek nymphaia and the Latin name nymphaea, which means "water lily". They were inspired by the nymphs of Greek and Latin mythology. Nymphaea flowers are occasionally fragrant and sometimes open during the day, sometimes at night.

Planting and care

Nymphaea tetragona is hardy to about -10°C (14°F). The rhizomes should be planted from March to June, 20 to 40 cm (8 to 16in) deep. The small rhizomes should only be submerged by 10 cm (4in) at first, increase the depth as the plants grow. Plant them in good, stone-free garden soil (never use horticultural compost, as it is too rich and promotes algae growth) in the sunniest spot. Space each rhizome at least 0.30 m (1ft) apart and plant them by inserting them vertically into the soil up to the collar. In a natural water feature (pond or lake), make sure that the water level remains fairly stable and that the water is neither too acidic nor too alkaline (desired pH between 6.5 and 7.5). The rhizomes can be planted in a wicker basket or a fine wire mesh basket placed at the desired location. For shallow ponds, planting in a bowl is possible, but it is essential to overwinter the rhizomes in damp sand protected from frost. If the bottom is muddy, simply attach a stone to the rhizome and throw the whole thing into the desired location. Never leave Nymphaea rhizomes exposed to the sun or air. to prevent them from drying out, plant them immediately upon receipt or purchase. If you have fish in your pond, it is a good idea to spread a thick layer of large gravel on the surface of the potted plant to discourage them from digging into the soil and clouding the water. Water lilies will develop best if they are planted in containers suitable for their growth. Water lilies are hungry plants, so distribute a balanced slow-release fertilizer during planting, and then every year at the beginning of the growing season (for example Osmocote 10-11-18-2 with a duration of 5-6 months). During the summer, remove excessive leaves from the centre of the clump and keep only the strongest ones. Also remove any yellowed or stained leaves, as well as any aquatic roots which emerge from the surface.
