Who can write better description and review, than Botanic Garden and research center Mt. Cuba?
"Prairie aster is an underused yet very attractive aster for early to mid-autumn with its stunning flowers, disease resistant foliage and vigorous growth. This clump forming aster produces abundant, pale violet-blue flowers with yellow centers. They are displayed on stiff, wiry stems giving the plant an open and billowy, cloud-like appearance. This perennial, with pale blue-green foliage and a 3′ tall, shrub-like form is drought tolerant and prefers sunny conditions. Prairie aster makes a fine addition to borders or meadow landscapes and combines nicely with Rudbeckia triloba, Solidago rugosa ‘Fireworks’, Euthamia caroliniana, and Schizachyrium scoparium."
Not many pure wildflower are highly recommended for landscaping, and with Asters it happened actually only with Aster divaricatus and Aster oblongifolius. Prairie aster is another one and is recommended by Chicago Botanic Garden - verified in aster trials and by Mt. Cuba, Delaware too. Native to Nebraska, Kansas, Oklahoma, Louisiana, Arkansas, Missouri, Iowa and Illinois.
Full sun, average soil, drained soil, rocky soil with average = medium moisture to dry soils. Healthy growth, high coverage with flowers. Great cut flower.
Excellent pollinator support - attracts various bees, bee flies, butterflies, skippers, and other insects. Bee visitors include honeybees, bumblebees, leaf-cutting bees, digger bees, and Halictid bees. Host plant for caterpillars of several butterflies and moths.
Unfortunately palatable to deer and rabbits.
