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.

Pinegrass is a hardy, native perennial grass common in forested regions of western North America. It is an important understory species and is typically found beneath conifer canopies. Due to its spreading nature and ability to form dense mats that cover the forest floor, it helps stabilize soils and reduce erosion.

It provides forage for wildlife and livestock, shelter for small animals, and seeds for birds, playing an important ecological role in woodland ecosystems. Pinegrass is well-suited for ecological restoration, soil stabilization, and naturalization projects.
