Beaked Sedge
Sweetgrass

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.

Sweetgrass is a cool-season perennial grass best known for its sweet, vanilla-like fragrance. The scent comes from coumarin in the leaves, which is pleasant to humans but has a bitter taste that makes the plant less appealing to deer and other herbivores. As a cool-season grass, Sweetgrass grows most vigorously in spring and fall, slowing or even going dormant during the heat of summer.

It spreads quickly through creeping rhizomes and can be difficult to remove once established, so it is best planted in areas where its spread will not cause problems. Due to its deep, vigorous root system and preference for moist soils, Sweetgrass is especially useful for erosion control, soil stabilization, riparian plantings, and naturalization projects.

Note: Sweetgrass was formerly classified under the scientific name Hierochloe odorata and its subspecies. The subspecies found in Canada are currently considered two distinct species: Anthoxanthum hirtum, which is native across Canada, and Anthoxanthum nitens, which is native to Eastern Canada. Because these two species are alike and share many overlapping common names, they are often considered as only one species.
