Here’s a frost aster that finds its niche in an Indianapolis sidewalk. One of the Symphyotrichum species with white flowers, probably Symphotrichum pilosum but could be Symphyotrichum ericoides or a hybrid of either. Whatever the species, these white asters are what you find in urbanized areas wherever a respite from lawn mowing happens for a season or two. Outside the city it’s known as oldfield habitat.
