Marsh Cinquefoil
Showy Aster

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.

Showy Aster is a native perennial wildflower recognized for its tall stems topped with clusters of light purple blooms. Blooming from late summer into autumn, it provides an important late-season source of nectar and pollen for pollinators. It also produces seeds that are eaten by birds, extending its value to wildlife beyond the flowering season.

Drought tolerant once established, Showy Aster grows well in urban, rural, and disturbed sites. With its mix of ecological value and ornamental appeal, it is ideal for pollinator gardens, naturalization projects, and ecological restoration.
