Marsh Cinquefoil
Water Sedge

Marsh Cinquefoil is a native perennial wetland plant with striking reddish-purple, star-shaped flowers. They bloom in early to mid-summer, providing nectar for bees, flies, and other pollinators. Beyond its summer blooms, the foliage turns red in autumn, adding seasonal interest to wetland landscapes.

Common in wetlands, pond margins, and wet meadows, Marsh Cinquefoil spreads by rhizomes to form colonies or patches that contribute to shoreline stabilization. It thrives in nutrient-poor, saturated soils where many other plants struggle, making it valuable in challenging wetland conditions. With its ecological function and ornamental appeal, it is well-suited for wetland plantings, ecological restoration, and naturalized projects.

Water Sedge is a waterside grass which grows an extensive horizontal root system. This prevents erosion and allows it to grow back after being eaten.

Water sedge is grazed by many animals including cattle, sheep, horses and waterfowl. Animals choose Water Sedge for forage later in the year as it stays green longer than other plants, requiring you to buy feed for less of the year.
