Wild Bergamot
Sweetgrass

Wild Bergamot is a native perennial wildflower that is known for its fragrant lilac-purple tubular flowers. The flowers grow in dense terminal heads and bloom from mid-summer to early fall. Deadheading spent flowers will encourage new blooms, prolonging its display. They attract pollinators such as bees, butterflies, and hummingbirds. It also serves as a host plant for the Raspberry Pyrausta (Pyrausta signatalis) butterfly.

Wild Bergamot belongs to the mint family, and its leaves, stems, and flowers are all edible. The leaves can be used to make tea or as a flavorful herb, with a taste often described as a blend of oregano and thyme.

It is resistant to deer and rabbits but can be susceptible to powdery mildew if planted too densely with poor air circulation. Wild Bergamot tolerates heat, drought, and poor soils, making it a low-maintenance addition to a variety of projects. It is well suited for pollinator gardens, wildflower gardens and naturalization projects.

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.
