I planted this grass by seed in full shade about 5-6 years ago. I like the appearance and it came up well from seed. Over the last 5 years I have watched it slowly move from the top of the hill where it was originally planted down the hillside and into the sun. It doesn’t seem to mind the sun at all and it never gets supplemental watering. Now it is pretty well established on the hillside in full sun. I am curious to see whether it continues to spread in its new location.
