Canary-yellow flowers stand above the water. The foliage is very prolific, though the plant is not particularly free-flowering. Over time, it can grow into water up to 3 metres. It is classed as Viviparous as it occasionally grows new plants from its leaf stems.
Care Guide for Nymphaea Water Lilies:
Lighting: Nymphaea water lilies thrive in full sun to partial shade. They require a minimum of 5-6 hours of direct sunlight each day for optimal flowering. In outdoor ponds or water gardens, ensure that the plant receives ample sunlight. If the sunlight is too intense, provide some shade during the hottest part of the day to prevent leaf burn.
Water: Water lilies are aquatic plants and require water to grow. They prefer still or slow-moving freshwater environments, such as ponds or water gardens. The water depth should be appropriate for the variety, with the leaves floating on the water surface. Maintain a water temperature between 70-85°F (21-29°C) for optimal growth and flowering.
Nutrient Requirements: Nymphaea water lilies benefit from regular fertilization to promote healthy growth and abundant blooms. Use a specialized aquatic plant fertilizer formulated for water lilies. The fertilizer should be rich in essential nutrients, such as nitrogen, phosphorus, and potassium. Follow the manufacturer's instructions for dosage and frequency, as excessive fertilization can lead to algae overgrowth.
Water Quality: Maintain good water quality to support the health of your water lily and other aquatic organisms. Regularly test the water for pH, which should be slightly acidic to neutral (around 6.5-7.5). Ammonia and nitrate levels should be kept low, as they can harm the plant. Perform regular water changes and use a mechanical filter to remove debris and excess nutrients.
Planting: When planting a water lily, ensure that the rhizome is positioned correctly. The rhizome should be planted horizontally in a container with a suitable aquatic planting medium. The container should be placed at the appropriate depth, allowing the leaves to float on the water surface. Avoid burying the rhizome too deeply, as it can inhibit growth.
Pruning: Regular pruning is essential to maintain the health and appearance of your water lily. Remove yellowing or decaying leaves and spent flowers. Trim back overgrown or crowded leaves to allow for proper light penetration. Pruning also helps control the plant's spread and prevents overcrowding in the water garden.
Winter Care: Most water lilies are hardy and can withstand cold temperatures. However, if you live in an area with harsh winters, it is recommended to protect the plant by moving it to a deeper part of the pond or using a floating de-icer to prevent freezing around the plant. In extreme cold regions, you can lift the plant and store it in a frost-free area until spring.
Remember, the specific care requirements may vary depending on the exact variety of your water lily. It's always best to consult with local nurseries or aquatic plant experts who may be familiar with the specific variety you have to get more tailored care instructions.
