I find this plant to be more tolerant of full sun than most books say. I started off with a flat of plugs and after a few years the plants are spreading nicely and re-seeding here and there on their own. They plant themselves in full sun, and these plants do just as well as the ones that are in partial shade. I don’t give them any special watering even in periods of drought, and I have the typical Tennessee clay soil. Also I was warned by a friend that this grass can be aggressive. However, I need a grass that will fill in on its own without me having to buy 100s of plants, plus it is so attractive that I am glad for every plant that I get. It is not like Big Bluestem that will crowd out every flower you have.
