This plant is native to wetlands, ponds, and slow-moving streams across Europe and Asia. It is characterized by its distinctive arrow-shaped leaves and small, white flowers. Sagittaria sagittifolia plays a significant role in its ecosystem, providing habitat and food for various wildlife species. It is also cultivated for its edible tubers in some regions.

Description

Sagittaria sagittifolia is a perennial, herbaceous plant that can grow up to 30 cm in height. The leaves are glossy, green, and arrow-shaped, which is the origin of its common name.
