Blue Grama Grass
Anise Hyssop

Blue Grama is a native perennial bunchgrass recognized for its blue-green blades and unique seed heads. They grow along one side of the stem and are often compared to eyelashes, eyebrows, or mosquito larvae, which inspired its common names, Eyelash Grass and Mosquito Grass. As the seed heads begin to dry in the fall, they curl, further enhancing the plant’s distinctive appearance. The seeds provide food for birds, and the grass serves as a host plant for certain species of skipper butterflies.

As a warm-season grass, Blue Grama has a slow start in spring and does not actively grow until soil temperatures rise. Its deep roots help with erosion control, and the grass is drought-tolerant once established, thriving even in poor or alkaline soils. It is well-suited for soil stabilization, naturalization, restoration projects, or as an ornamental accent in gardens and landscapes.

Anise Hyssop is a native perennial wildflower known for its fragrant spikes of small purple flowers. This plant is an excellent source of nectar and is highly attractive to a variety of bees and other pollinators. Deadheading spent flowers will encourage more blooms throughout the season.

Its aromatic leaves release an anise-like (licorice) scent when crushed. Both the leaves and seeds are edible and have been used in teas and as flavouring. Leaves can be harvested at any time, though the oil content is highest just past full bloom. Deer tend to avoid Anise Hyssop because of its strong-smelling leaves. This makes it a useful plant for positioning as a protective border around more vulnerable species.

Anise Hyssop spreads by seeds and rhizomes, but is less aggressive than other members of the mint family and is easy to remove if needed. Historically, it was planted in large numbers as a honey plant to support apiaries. Birds also feed on its seeds, adding to its ecological value.

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.
