Showy Aster
Anise Hyssop

Showy Aster is a native perennial wildflower recognized for its tall stems topped with clusters of light purple blooms. Blooming from late summer into autumn, it provides an important late-season source of nectar and pollen for pollinators. It also produces seeds that are eaten by birds, extending its value to wildlife beyond the flowering season.

Drought tolerant once established, Showy Aster grows well in urban, rural, and disturbed sites. With its mix of ecological value and ornamental appeal, it is ideal for pollinator gardens, naturalization projects, and ecological restoration.

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.
