Snowball Viburnum

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.

Snowball Viburnum is a popular ornamental shrub with prolific flowering. This plant is prized for its round clusters of white flowers that resemble snowballs, delighting children and adults. In fall, its leaves turn vibrant shades of red.

Snowball Viburnum is sought after as a single accent shrub, but can also make a dense hedge or privacy screen.
