Aster oolentangiense = A. azureus (Symphyotrichum) - SKY BLUE ASTER
Adaptable native wildflower, important late source of nectar and pollen for native bees, various butterflies including Monarch butterflies and other insects. Seeds feed the birds.
3' tall x 1' wide upright and a bit leggy looking plants. Violet-blue flowers in August/September and October.
Full sun, half shade, any soil that is drained (don't plant into waterlogged soils). Average moisture to drier soils - loam, clay, rocky, sandy, gritty.
Drought and black walnut tolerant.
Suitable for zones 3 to 8.
Native to central, eastern USA, deep south, most of Midwest and Canada, see the BONAP distribution map.
Can be found in better quality habitats - in mesic to dry prairies, sand prairies, hill prairies, rocky upland woodlands, woodland edges. sandy meadows, limestone glades, along roads.
Mammals (including deer and rabbits) feed on the foliage, but usually only on the fresh new leaves and stems in the first half of the season.
Flowers attract many native bees (bumblebees, digger bees, leaf-cutting bees, Halictid bees, Andrenid bees), Syrphid flies, bee flies, butterflies, skippers, miscellaneous beetles, and other insects.
Host plant for many small bugs, leafhoppers, grasshopper, larvae of the butterflies Silvery Checkerspot, Pearl Crescent and several moths. Ruffed Grouse, Wild Turkey browse on the leaves and seeds, Tree Sparrow eat the seeds during the winter.
Easy to grow beneficial wildflower, that can be used for prairie plantings, meadows, dry meadows, naturalistic planting, for naturalization, in pollinator, butterfly, Monarch or bird gardens. Showy plant with ephemeral look.
