Wheat Sedge
Showy Aster

Wheat Sedge is a native perennial sedge commonly found in wetlands, ditches, and along shorelines. It thrives in saturated soils, spreading by rhizomes to form large colonies that stabilize both soils and shorelines. This makes it valuable for wetland and riparian plantings.

Its distinctive, wheat-like seed spikes add seasonal character while providing food for waterfowl, and its dense clumps supply cover and nesting habitat for birds and small animals. Together, these traits make Wheat Sedge an important species for enhancing biodiversity and supporting healthy wetland ecosystems.

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.
