Sagittaria sagittifolia, commonly known as Arrowhead or Common Arrowhead, is a perennial aquatic plant in the Alismataceae family. Native to Europe and Asia, this plant is well-known for its distinctive arrow-shaped leaves and its ability to thrive in wet environments such as ponds, lakes, marshes, and slow-moving streams. It is a popular choice for water gardens and naturalized aquatic landscapes due to its ornamental appeal and ecological benefits. Arrowhead typically grows to a height of 1 to 3 feet, with a spread of about 1 to 2 feet. The plant features striking, arrowhead-shaped leaves that are bright green and can reach up to 12 inches in length. These leaves are borne on long, sturdy petioles that rise from a submerged rhizome. The foliage emerges from the water, creating a lush, vertical display that adds texture and interest to aquatic settings. From mid-summer to early autumn, Sagittaria sagittifolia produces clusters of small, white flowers with three petals. Each flower is about 1 inch in diameter and is held on tall, erect stems above the foliage. The flowers have a simple, elegant beauty and are followed by small, green seed pods. These flowers attract various pollinators, including bees and butterflies, enhancing the ecological value of the plant. Arrowhead prefers full sun to partial shade and thrives in shallow water up to 12 inches deep, making it ideal for the edges of ponds, lakes, and other water features. In terms of care, Sagittaria sagittifolia is relatively low-maintenance. It benefits from regular watering to maintain its preferred moist conditions and can be fertilized occasionally to promote vigorous growth and flowering. Overall, Sagittaria sagittifolia is a versatile and attractive aquatic plant that enhances the beauty and ecological health of water gardens and wetland areas. Its distinctive foliage and charming flowers make it a valuable addition to gardens focused on aquatic and marginal plants.
