Smooth Aster
Symphyotrichum laeve
Notes:

From what I've read, Asters are one of the best caterpillar host plants. The adult pollinators also like them.

One of the Smooth Asters got eaten by rabbits in early summer about three straight years. But from what I've heard and read, most native plants are used to getting chewed on. This flower survived and is doing well.

We abuse land because we regard it as a commodity belonging to us. When we see land as a community to which we belong, we may begin to use it with love and respect.
