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.

I think the environment should be put in the category of our national security. Defense of our resources is just as important as defense abroad. Otherwise what is there to defend?
