revegetation of washout area

The washout area has been slowly becoming revegetated. In the winter and early fall, we planted seeds and a few plants in hoping to control some of the erosion. Now, the area is becoming revegetated. Wildflowers such as Clasping Coneflower, Goldenwave , Scarlet Sage, and a handful of sunflowers. The short grasses that spread in the fall have begun to die back and the tall grasses are beginning to sprout and seed. Unfortunately, I don't know the names of grasses as well as wildflowers. The virginia sweetspire died probably due to the dry June that we had, but the False Indigo is thriving, probably because its native riparian background. Even one of the inland seaoats has survived long enough to send out seeds.
