Upright Prairie Coneflower
Sweetgrass

Upright Prairie Coneflower is a native perennial wildflower known for its vibrant flowers, which range from golden yellow to dark rust-red with yellow edges. Rising on tall, slender stems, the flowers’ drooping petals surround a central cone. They bloom from midsummer into fall, attracting butterflies, bees, and other pollinators. After blooming, the florets on the cone eventually develop into seeds, which provide a food source for birds.

Its upright growth habit allows it to grow in clusters, creating a striking display. Due to its deep taproot, Upright Prairie Coneflower is drought tolerant, making it well suited to dry areas and xeriscape gardens. Low-maintenance and deer-resistant, this wildflower is a great choice for adding vibrant color and ecological value to any landscape.

As a perennial, it dies back to the crown each winter, it will regrow from the base in the spring. Avoid disturbing the crown during late winter to ensure healthy growth the following season.

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.
