About

Myriophyllum alterniflorum, known as alternate water-milfoil or alternateflower watermilfoil, is a species of water-milfoil. It is native to Europe and Asia, has been introduced to North America and inhabits aquatic habitat, such as ponds and streams.

Where it grows

M. alterniflorum is found in more shallow areas in bodies of water (e.g., rivers and lakes), in order for these plants to survive in these areas the water needs to be slow moving. The preferred type of water tends to be fresh or even brackish water (i.e., salt and freshwater mixed together). These plants tend to be cultivated in more sandy and mucky types of environments, due to the pH preference being 5.4–11 pH level. This is considered to be an alkaline environment, where the plant tends to thrive best in.
