Showy Aster
Twinflower

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.

Twinflower is a native, trailing evergreen ground cover known for its delicate flowers that grow in nodding pairs. These pale pink blooms are described as being sweetly fragrant, attracting native bees and other pollinators.
Growing in cool, moist, acidic soils, the trailing stems form roots as they spread and start to form mats across the forest floor. Due to its woody stem, it is technically classified as a shrub and often referred to as a subshrub or dwarf shrub. This species is well-suited for naturalization, restoration, and conservation projects.
Twinflower (Linneae borealis) was named in honour of Carl Linnaeus, who adopted it as his personal emblem.
