Showy Aster
Lewis Mock Orange

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.

Lewis Mock Orange is a flowering ornamental shrub that produces an abundance of white, fragrant blooms. The flowers have a sweet scent similar to orange blossoms, with a hint of pineapple. They bloom for several weeks from late spring to early summer, attracting pollinators and other beneficial insects.

Native to North America, Lewis Mock Orange is found from the southernmost portions of Alberta and British Columbia, and south into the northwestern United States. It makes an attractive shrub and can be used in hedgerows, pollinator gardens, and naturalization projects. Blooms occur on the previous year’s wood, so it is recommended to prune after it has finished flowering.
