How to Grow and Care for Sky Blue Aster Symphyotrichum oolentangienseOrnamental sky blue aster, Symphyotrichum oolentangiense, formerly Aster azureus, is a native herbaceous perennial that readily naturalizes in USDA Hardiness Zones 3 to 8.
It toils away all season long, forming branching foliage. Then it bursts into masses of blue, daisy-like flowers, just in time to bridge the gap between summer’s waning blooms and fall’s spectacular leaf show.
This member of the Asteraceae family has an upright growth habit. Dense basal foliage thins out along branching stems that culminate in loose, cone-shaped floral clusters.

The shade of blue may vary from deep to pale, or it may be slightly purple.
In this article, you’ll learn how to grow and care for vigorous sky blue aster in your outdoor living space.
Cultivation and HistoryListed as an endangered species in New York, sky blue aster is prized by native plant enthusiasts.
According to the New York Natural Heritage Program, a botanist by the name of John Leonard Riddell was the first to name the lovely blue flower he found growing by the Olentangy River in Ohio, in 1835.
He identified it as Aster oolentangiensis, misspelling the river reference. Later it was reclassified Aster azureus as a member of the Aster genus, which contained over 500 species at the time.
During the 1990s, research revealed that the US native asters have their own unique evolutionary history, and as such they were reclassified into different genera.
