erosion

For the last few weeks, I've been checking on the wax myrtles and yaupon hollies that Jim, Eileen, Michele and I had planted at the washout area. Until yesterday, about 6 of them had survived and though not grown much above the ground had remained green. When Michele and I went yesterday to plant some wildflower seeds, we found that the soft ground above had given way and the plants were now covered by about a foot of soft clay. We went ahead and sowed the wildflower seeds in hopes that it would provide some erosion control. The seeds were a mix from Native American Seeds , the drainfield mix which is suitable for wet environments such as this one. It contains the following wildflowers:
Clasping Coneflower
Cutleaf Daisy
Scarlet Sage
Plains Coreopsis
Illinois Bundleflower
Black-eyed Susan
Pink Evening Primrose
Maximilian Sunflower
Obedient Plant
Pitcher Sage
