Slough Grass

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.

Slough Grass is a hardy grass that will happily grow in any wet soil. It is usually found near water and is common haymaking material or forage.

Slough Grass is also useful for erosion control and land reclamation.
