Cyperus-like Sedge vs Sulphur-Flower Buckwheat

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.

Sulphur-Flower Buckwheat is a native perennial wildflower known for its dense clusters of cream to yellow flowers. The long-lasting blooms persist from late spring into summer, providing an extended nectar source for a variety of pollinators. The flower buds are often red-tinted before opening. As the blooms age, they shift to orange or red, adding seasonal interest and making them well-suited to dried flower arrangements. Its seeds are also eaten by birds, adding to its ecological value.

Depending on climate and conditions, Sulphur-Flower Buckwheat may be evergreen to semi-evergreen, or its foliage may turn red during fall. Its deep roots and spreading growth stabilize rocky or sandy soils, making it useful for erosion control. Exceptionally hardy once established, it requires little care and thrives in challenging environments, making it an excellent choice for pollinator gardens, naturalization, and ecological restoration projects.
