Description

Nymphaea 'Conqueror' is a hardy water lily of large size that produces large double flowers mottled with purple red on a white background. These flowers bloom among large round green leaves throughout the summer. This vigorous variety is suitable for medium to large bodies of water. Its rhizome should be planted 40cm to 1m below the surface. It is a very floriferous and colorful water lily that stands out in a pond.

The hybrid Nymphaea 'Conqueror' is a horticultural creation by Latour-Marliac (France) dating back to 1910. It is a aquatic perennial with deciduous foliage that belongs to the Nymphaeaceae family. This plant develops numerous floating leaves measuring 16 to 20cm in diameter in mature plants starting from spring. The leaves are round, sometimes undulate, and their sinus is normally open two-thirds, sometimes completely open or almost closed. When young, they are bronze in color and gradually turn to shiny dark green. The plant, particularly vigorous, spreads over 1.50m and more. The generous flowering usually begins in June and continues until late summer. The flowers, composed of 25 petals, measure 14 to 18cm in diameter and bloom on the surface. Their colour is precisely described by Latour-Marliac as follows: "bright red, with white petals on the concave side and veined with red on the convex side; yellow-orange stamens." These corollas open during the day and close in the evening. Each flower lives for 4 to 5 days before wilting, it returns underwater and is replaced by another flower. The flowering is followed by the formation of fruits containing numerous seeds. The fruit ripens underwater and releases floating seeds that will eventually sink and germinate in the mud. Water lilies are hardy as long as their rhizome does not freeze in winter. It is important to ensure that the water does not freeze at the depth where they are installed.

Choose varieties of water lilies that are easy, hardy, and floriferous, and above all, those that are proportionate to your pond. With their perfectly shaped flowers, Nymphaeas are among the most beautiful pond plants. 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 water oxygenation. Their leaves floating on the water's surface will provide shade and shelter for your fish, which in turn 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 bears flowers that are sometimes diurnal, sometimes nocturnal, and occasionally fragrant.

Planting and care

The rhizome of the 'Conqueror' water lily should be planted from March to June at a depth of 40cm to 1m (up to 1.20m below the surface). Plant the rhizomes of hardy water lilies in good garden soil, rich in clay or silt, and free of stones (never use potting soil, as it is too rich and promotes algae growth). Give them the sunniest spot in the water feature. Space each rhizome at least 1m 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), make sure 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 mesh basket that is sunk in the desired location. For classic hardy water lilies, use a pot with a diameter of 40cm (wider than it is tall). If the bottom is muddy, simply attach a stone to the rhizome and throw the whole thing to 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 deter them from digging into the soil and thus fouling the water. The growth of water lilies will be optimal if they are planted in containers suitable for their growth.

Water lilies are hungry plants: distribute a balanced slow-release fertilizer at 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 any leaves that grow in excessive numbers in the centre of the clump, keeping only the most vigorous ones. Also remove any yellowed or stained leaves, as well as emerging aquatic "weeds".
