Junegrass is a native, low-growing perennial bunchgrass commonly found in prairies and open woodlands. It is a great choice for prairie restoration and naturalization projects or an attractive accent in ornamental plantings. Spear-shaped seed heads rise above the gray-green lower leaves, maturing to a tan color. Flowering earlier than other upright prairie grasses, it greens up quickly in spring and maintains its appeal well into the fall. It is shorter in stature and rarely forms thick stands, which adds to its understated visual appeal.

Adapted to cooler climates, Junegrass thrives in well-drained, rocky, sandy, or gritty soils and can tolerate drought, cold, and high altitudes. It actively grows in spring and fall when soil temperatures are cool, but in areas that are too hot or humid, it may go dormant by late summer.

As a perennial, it dies back to the crown each winter, it will regrow from the base in the spring. Avoid disturbing the crown during late winter to ensure healthy growth the following season.

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.
