Showy Aster (Aster spectabilis)
ASS-ter spek-TAB-ill-iss

Deciduous Perennial Low, Spreading in the Asteraceae Family
A rare, sand-loving native prized for having some of the biggest flowers of any wild aster - big lavender-blue, yellow-centered blooms on a low, spreading clump from late summer into fall.

Aster spectabilis (Eurybia spectabilis), commonly known as Showy Aster or Purple Wood-Aster, is a low, spreading perennial native to sandy pine barrens and dry woodlands along the Atlantic coast. True to its name, it produces some of the largest flowerheads in the aster family, up to 1.5 inches across, in bright lavender-blue with vivid yellow centers, blooming from August into October. It forms a low, rhizomatous groundcover on stiff, rough stems, spreading gently through dry, sandy soil.

Pros

  • Some of the largest, showiest flowers of any native aster
  • Drought-tolerant and thrives in poor, sandy, dry soil where little else grows
  • Low, spreading habit works well as a groundcover
  • Strong pollinator draw for butterflies, bees, and hummingbirds

Cons

  • Native to sandy coastal habitats, not the Chicago region - provide well-drained, sandy soil for best results
  • Spreads by rhizomes and can creep beyond its original spot
  • Prefers dry, lean soil; can struggle in rich or consistently wet garden beds
Why Like

In its native pine barrens and dry, sandy woodlands along the Atlantic coast, Showy Aster is an important late-season nectar source, drawing butterflies, bees, and even hummingbirds when few other plants are still blooming. Its rhizomatous roots help stabilize loose, sandy soil.

Highlights

Noted for having some of the biggest flowerheads of any aster species, this low, spreading native is a standout in a dry, sandy garden where few other perennials thrive.

Field-Grown vs. Greenhouse-Grown Plants

Plants which are well-adapted to our local climate are most often field-grown (outside). Field-grown plants are generally cheaper and have the advantage of already somewhat acclimated to our cold winters, but that means they’re not artificially far along in the spring and tend to bloom at the normal time in our area.

Spring annuals and tender perennials are typically grown in Greenhouses so they can be ready and luxurious exactly when customers want them. Some perennials are also “forced” into early bloom in greenhouses. In May, there can be a very big difference between field-grown and greenhouse-grown plants of the same type. The latter typically look good right away (so they’re a great choice where that’s important), but we typically pay a premium for it.

No Pricing or Availability Right Now

We order from a rotating cast of the best nurseries in the Great Lakes region. It looks like we've offered this plant in the past, but the nurseries we're working with this week don't appear to have it in stock at the moment.

Our goal is to bring as many plants together under "one roof" as possible, so we'll try hard to make it available again in the future!
