About Whorled water-milfoil
Myriophyllum verticillatum, commonly known as Whorled Water-milfoil, is a submerged aquatic plant from the Haloragaceae family, valued for its delicate, finely divided leaves arranged in whorls along its stem. Its feathery, bright green appearance makes it ideal for freshwater aquariums, shallow ponds, or as a decorative element in water gardens. It adds a natural touch and provides excellent refuge for small fish and fry.
Native range
Widely distributed in the Northern Hemisphere (Europe, Asia, North America)
Care tips
This species thrives in clear, calm waters, preferring medium to high lighting to develop its optimal coloration and shape. While it can tolerate a wide range of temperatures, it benefits from a range between 18-28°C (64-82°F). Substrate is not crucial as it primarily absorbs nutrients from the water, but a nutrient-rich substrate or the addition of liquid aquatic plant fertilizers will promote its growth. Avoid sudden changes in water conditions, as this can lead to leaf drop.
