There are some advantages and disadvantages inherent with growing native plants in this location. One advantage is that this area warms up earlier in the spring and stays warmer in the fall because of the southern exposure and the reflected heat from the house. A disadvantage is that the area dries out really fast and even drought tolerant plants will sometimes look wilted. I don't generally advocate watering native plants, but I will on occasion turn a sprinkler on this area during really hot and dry time periods.
Here are three photos, starting with the third closest to the rear of the house (the west) and moving toward the front (east) of the house. Right now there isn't much blooming. This garden really shines in the late summer and fall when the majority of prairie/grassland plants come into bloom.
Here are the same photos with some plants labeled. Other flowers that are not visible or labeled include Swamp Milkweed, White Avens, Missouri Ironweed, and Ohio Goldenrod.
