About this Plant

Silky Aster is a small but striking prairie native known for its silvery foliage and rich purple flowers that bloom in early to mid-fall. The plant rarely exceeds 1–2 feet tall, forming a tidy mound well suited for rock gardens, dry borders, and tough sunny spots where few other natives thrive. Its foliage is covered in fine hairs, giving it a silky texture and bluish-gray hue that stands out against greener companions.

Its late-season blooms are a vital nectar source for butterflies and bees when few other native flowers are blooming. This aster's compact size and clumping habit make it easy to tuck into tight or dry spaces, especially where a splash of fall color and pollinator support is desired.

Why Choose Silky Aster?

Compact, clump-forming shape—great for rock gardens
Silvery, textured foliage adds contrast and interest
Excellent drought tolerance once established
Fall blooms support native pollinators
Grows in sandy, rocky, or poor soils with ease

Thrives in full sun and well-drained soils. Minimal maintenance needed—cut back in early spring if desired for tidiness. Divide every few years to refresh growth.
