Hi there. The purple flowering ground cover is Thymus serphyllum, Red Mother of Thyme. It is drought tolerant, salt resistant, good in most soils and also deer proof. I typically plant 4" pots, 18' on center in fertile mulch. I also spread corn gluten to inhibit seed germination while the plants quickly cover the area. The clump grass is Helictotrichon sempervirens, Blue Oat Grass. It is easily grown in average, dry to medium, well-drained soil in full sun. Best blue color occurs in dryish soils. Remove withered leaves as they appear. Although foliage is evergreen in warm winter climates, it is more semi-evergreen in harsh winters where foliage decline will occur. In the St. Louis area, plants generally benefit by being cut back close to the ground in late winter every year.

Hope this helps.
