This native perennial is aptly named, Frost Aster (Symphyotrichum pilosum). It is one of the last blooming perennials in Chicago-land, ending only when a hard frost sets the stage for winter’s dormancy. The abundance of blooms is magnified by the circumstance that the plant is a rhizome, existing as spreading gatherings of the parent plant. The previous post showed the Frost Aster along the lakefront path in Lincoln Park. Those colonies lived on the side of the wall opposite of Lake Michigan, preferring the dryer environment of a gravel path.
Attention is focused as the sun momentarily spot lights this bouquet. I centered the composition, to emphasize the natural vignette around this vibrant cluster.
May frost come later than sooner.
