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.

The old Lakota was wise. He knew that man's heart away from nature becomes hard; he knew that lack of respect for growing, living things soon led to lack of respect for humans too.
