Description

The Nymphaea 'Newton' is a hardy water lily whose almost red star-shaped flowers resemble those of tropical varieties. They are large, formed by long, slender petals, adorned with a superb bouquet of long stamens, and usually rise above the surface. This water lily has significant growth and is rather floriferous. This variety is suitable for medium to large bodies of water, ideally planted between 40 and 80 cm below the surface.

The Nymphaea 'Newton' is a horticultural creation by Latour-Marliac dating back to 1910. It is an aquatic perennial with deciduous foliage. It belongs to the family Nymphaeaceae. This plant develops numerous floating leaves measuring 20 to 25 cm in diameter starting from spring. The leaves are rounded and permanently open in a V shape. Their colour is olive green with a slight bronze border. The plant spreads over 1.20 m to 1.50 m. Flowering usually begins in June and continues until late summer. The flowers measure between 14 and 18 cm when fully open. When they bloom, they have a star-like shape and open almost flat. Their petals are thin, increasing in size from the centre to the periphery, ranging in colour from red to pink. The centre is filled with numerous fine and very long stamens in shades of red, orange, and yellow. These flowers are solitary, floating or held a few cm above the water. They open during the day and close in the evening. The flowering is followed by the formation of fruits containing numerous seeds. The fruit ripens underwater and releases floating seeds that eventually sink and germinate in the mud. Water lilies are hardy as long as their rhizome does not freeze in winter. It is essential to ensure that the water does not freeze at the depth where they are planted.

Choose varieties of water lilies that are easy, hardy, floriferous, and, above all, proportionate to your pond. Water lilies are among the most beautiful perennial pond plants with their perfectly shaped flowers. Most of them bloom for long weeks until early autumn. Water lilies are essential aquatic plants for maintaining the balance of a garden pond, as they contribute to the oxygenation of the water. Their floating leaves provide shade and shelter for your fish, protecting them from predatory insects such as aphids.

The genus name comes from the Greek nymphaia and the Latin name nymphaea, which means "water lily". The nymphs of Greek and Latin mythology inspired them. Nymphaea produces flowers that are sometimes diurnal, sometimes nocturnal, and occasionally fragrant.

Planting and care

The rhizome of the 'Newton' water lily should be planted from March to June at a depth of 40 to 80 cm (maximum 1 m). Plant the rhizomes of hardy water lilies in good garden soil, rich in clay or silt and free from stones (never use horticultural compost, as it is too rich and promotes algae growth). Give them the sunniest spot in the water feature. Space each rhizome at least 1 m apart and plant them by inserting them vertically into the soil up to the collar. In the case of a natural water feature (pond or lake), ensure that the water level remains relatively 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 mesh basket that is sunk into the desired location. For classic hardy water lilies, use a pot with a diameter of 40 cm (wider than it is tall). If the bottom is muddy, attach a stone to the rhizome and throw the whole thing into the desired location. Never leave the Nymphaea rhizomes exposed to the sun or air to prevent them from drying out; plant them as soon as you receive or purchase them.

If you have fish in your pond, it is preferable to spread a layer of coarse gravel on the surface of the planted pot to discourage them from digging into the soil and thus fouling the water. The growth of water lilies will be optimal if planted in suitable containers for their development.

Water lilies are hungry plants: distribute a balanced slow-release fertiliser at planting and 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 any leaves that grow in excessive numbers in the centre of the clump, leaving only the most vigorous ones. Also, remove any yellowed or stained leaves and any aquatic "weeds" that emerge from the surface.
