Yellow Mountain Avens
Anise Hyssop

Yellow Mountain Avens is a native perennial wildflower with bright yellow buttercup-like blooms. The nectar-rich flowers attract a variety of pollinators, including bees and butterflies. By thriving at higher elevations, it helps sustain pollinator populations and provides one of the earliest sources of nectar and pollen in alpine habitats.

As a nitrogen-fixing plant, Yellow Mountain Avens enriches soil fertility and supports the growth of surrounding vegetation. It forms dense, spreading mats of evergreen foliage that act as a groundcover and help stabilize soil. Often among the first species to establish in disturbed alpine sites such as glacial outwash or landslides, it is well-suited for alpine revegetation, erosion control, naturalization, and ecological restoration projects in harsh, rocky environments.

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.
