  • water dropWater

    The Fringed Water Lily, being an aquatic plant, does not require watering in the traditional sense. It should be grown in shallow water, where it can ideally have 1-1.5 feet of water above the soil level in which it's planted. Instead of watering, ensure that the water levels are consistent and top up as necessary to combat evaporation. There's no fixed schedule for adding water, but monitoring every few days, especially in hot weather, is important to maintain proper water levels. As it grows in a water environment, there's no need to measure water in ounces or gallons for watering purposes, just maintain the appropriate depth of water for the plant's health.

  • sunLight

    Fringed Water Lily thrives in full sunlight but can tolerate partial shade. It is best situated in a spot where it can receive at least six hours of direct sunlight daily. The ideal location for optimal growth is an area with unfiltered and unobstructed access to sun rays throughout the day.

  • thermometerTemperature

    Fringed Water Lily performs well in a temperature range between 50°F and 77°F. The plant can survive a slight drop below this range but should not be exposed to temperatures below freezing, as this can cause damage or death to the plant. Consistently warm temperatures within this range promote the best growth and flowering.

  • scissorsPruning

    Pruning of the Fringed Water Lily involves removal of yellowing or dead leaves to encourage healthy growth and improve aesthetics. This should be done as needed throughout the growing season. Additionally, trimming can help manage the spread of the plant, as it has tendencies to take over space. The best time for pruning is during the plant's active growth phase in spring and summer.

  • circleLife cycle

    Fringed Water Lily begins its life cycle as a seed, which germinates in spring in the muddy bottoms of freshwater bodies. It then grows into a juvenile plant with a rosette of submerged leaves, and as it matures, it develops floating leaves and a robust root system anchored in the sediment. In summer, the adult plant produces distinctive yellow flowers that float on the water surface, each with fringed petals. After pollination by insects, these flowers produce seed capsules that sink to the bottom, releasing seeds that can remain dormant until the next growing season. In autumn, the above-water parts of Fringed Water Lily die back, but the plant survives the winter as dormant rhizomes or as seeds in the sediment. With the arrival of warmer temperatures in spring, the cycle begins anew with the germination of seeds or the sprouting of new shoots from the rhizomes.

      Spring to Summer

    • The most popular method of propagating the Yellow Floating Heart is by division. This is typically done in the spring or early summer when the plant's growth is most vigorous. To propagate by division, carefully remove the plant from the water and gently separate the rhizomes, ensuring that each section has at least one growing point or shoot. These divisions can then be planted in containers filled with loamy soil and submerged in shallow water, allowing the roots to establish. Once the plants show signs of new growth, they can be placed in their final positions within a pond or aquatic garden. This method is effective and allows for a quick increase in the number of plants.
