Grape Crush Aster
Deep Purple Daisies on a Neat Fall Mound
Grape Crush Aster (Symphyotrichum 'Grape Crush') saturates the autumn garden with masses of deep grape-purple, yellow-eyed daisies on a dense, naturally rounded mound. This native-type aster keeps its foliage clean and tidy while serving as a vital late-season nectar source for monarchs and native bees. Its rich color and compact habit make it a standout for pollinator borders and containers in Eden Prairie, Plymouth, and Eagan.

Landscape Uses
Use Grape Crush in pollinator and native gardens, mixed borders, and containers. Its tidy mound pairs beautifully with ornamental grasses, sedum, goldenrod, and other asters.
Best Time to Plant
Plant in spring or early fall. Spring planting gives the longest establishment window before winter.
How to Plant
Dig a hole twice as wide as the root ball and just as deep. Set the crown level with the soil, backfill, water in well, and mulch 2–3 inches deep, keeping mulch off the stems.
Watering
First Year: Water deeply 1–2 times per week to establish the roots.
After Year One: Water during dry spells. Asters are fairly drought tolerant once established but bloom best with occasional water.
Drip Irrigation: A drip line keeps moisture even without wetting foliage, which helps prevent mildew.

Is Grape Crush Aster Right for Your Yard?
It's an easy fit for full sun to part shade in average, well-drained soil, and earns its keep as one of the last big nectar sources before frost. Deer tend to pass it by. Not a fit if your spot is deep shade or stays soggy — bloom thins in shade and wet ground invites root problems.
