About Common water plantain
Alisma plantago-aquatica, commonly known as European water-plantain or Vassgro, is a perennial aquatic plant native to Eurasia and North Africa. Its broad, oval to lance-shaped leaves emerge from the water, while small white or pinkish flowers are borne in a pyramidal inflorescence. It is ideal for ponds, wetlands, or the margins of water bodies, adding a natural and rustic touch to the aquatic landscape.
Native range
Europe, Asia, and North Africa
Care tips
It prefers full sun to partial shade and a nutrient-rich substrate, preferably muddy or silty, at the bottom of the pond. Maintain a consistent water level, ensuring the base of the plant is always submerged, with at least 5-30 cm (2-12 inches) of water above the substrate. Fertilization is usually not necessary if the pond has a balanced ecosystem, as it draws nutrients from the sediments. Avoid planting it in pots that are too small, which can restrict its root development.
