Myriophyllum simulans

Common Name:

Amphibious Milfoil

Description:

Myriophyllum simulans, commonly known as Amphibious Milfoil, is a delicate and adaptable aquatic plant native to Australia. It is typically found in still or slow-moving freshwater environments such as creeks, wetlands, and pond margins. This species exhibits fine, feathery, whorled foliage that can vary in colour from green to reddish depending on water conditions and exposure. It grows submerged or emersed and can form floating mats or upright emergent stems, depending on the habitat. In Melbourne gardens, Myriophyllum simulans is excellent for naturalistic water features, wetland-style planting zones, and ecological restoration projects. It helps stabilise soil, improves water quality, and provides shelter for aquatic life. This plant produces small, inconspicuous reddish flowers that emerge at the base of the leaves during the warmer months.
