Narrow-Leaved Coneflower is a native perennial wildflower known for its pink to pale purple, daisy-like blooms. The petals (rays) droop downwards, around a dark, domed center, giving the flower a cone-like appearance. The nectar-rich blossoms attract a wide variety of pollinators, including native bees and butterflies. After flowering, the seeds provide food for birds, further adding to its ecological value.

Once established, it is drought-tolerant due to its deep taproot, which also helps stabilize soil. Narrow-Leaved Coneflower thrives in a variety of well-drained soils, including sandy, rocky, and alkaline. It often grows alongside the native grasses that characterize prairie and grassland ecosystems, making it well-suited for prairie and grassland restoration, naturalization, and pollinator gardens.

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.
