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.

Buttonbush is a moisture loving shrub that provides year round interest.

It has round, fragrant flowers resembling small buttons or pincushions. The flowers transform into small reddish-brown fruit that persists into winter while the leaves take on shades of red in fall.

Providing essential food to bees, butterflies, and other insects, this shrub is versatile. Try it in your next shrub border.
