Sweetgrass vs Baltic Rush

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.

Baltic Rush is a widespread native perennial rush that forms dense clumps of upright, cylindrical stems. Well adapted to saturated soils, it is common in wetlands, streambanks, and riparian zones, and is tolerant of both fresh and saline conditions. Hardy and low-maintenance, Baltic Rush contributes to soil stabilization and enhances wetland habitats.
It offers cover for small animals, nesting habitat for birds, and limited forage for livestock when young and tender. Its dense growth and rhizome networks add structural diversity that supports wetland ecosystems, making it well-suited for riparian planting, shoreline stabilization, wetland restoration, and reclamation projects.
