Cyperus-like Sedge
Showy Aster

Cyperus-like Sedge is a native perennial sedge found in wetlands, marshes, swamps, and along shorelines. Classified as an obligate wetland species, it grows in dense clumps that thrive in saturated soils, helping stabilize wet ground and protect shorelines. These colonies also provide cover for wildlife, while the seeds may be eaten by waterfowl and other birds. It is well-suited to wetland restoration, waterside and riparian zone plantings, and naturalization projects.
Its ornamental appeal comes from the contrast between the upright male floral spikes at the top of the stems and the long, drooping female floral spikes that hang below. These seed spikes resemble those of Cyperus species, giving the plant its common name and making it an attractive addition to naturalized plantings.

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.
