Myriophyllum crispatum

Myriophyllum crispatum, or Upright Water-milfoil, is a perennial aquatic herb native to Australia, typically found in freshwater wetlands, lakes, and slow-moving waterways. This submerged or emergent plant features finely divided, feathery leaves arranged in whorls along its stems, giving it a delicate, lace-like appearance. During its flowering season, small, inconspicuous reddish flowers are borne in clusters, adding subtle interest to aquatic habitats.

Thriving in shallow to deep freshwater environments, Upright Water-milfoil is highly valued for its role in wetland ecology. It helps stabilize sediments, improve water quality by trapping suspended particles, and provides habitat and shelter for aquatic invertebrates, fish, and amphibians. The plant is also a food source for waterbirds.

With its graceful form, ecological importance, and ability to enhance water clarity and biodiversity, Myriophyllum crispatum is an essential component of wetland restoration projects, riparian plantings, and aquatic garden designs.
