Beaked Sedge
Sulphur-Flower Buckwheat

Beaked Sedge is a native perennial wetland plant that forms dense clumps of tall, grass-like stems. It produces distinctive beaked seed heads that mature from late spring into summer. The plant provides food for waterfowl, muskrats, and other wildlife, while its dense growth offers cover for birds and small mammals. Its flowers and seed structures contribute to pollinator and invertebrate habitat in aquatic ecosystems.

Thriving in saturated soils and shallow water, Beaked Sedge is common in marshes, fens, and riparian zones. Its rhizomatous growth enables it to spread into large colonies that stabilize soils and support overall wetland health. Hardy and low-maintenance once established, it is well-suited to riparian plantings, naturalization, and ecological restoration projects.

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.
