Hi Sheri-
I have Angelina in my hideous acidic clay, likely similar to yours, deposited by glaciers, with rocks. . Angelina here grows great where I have it, spreads fast, I pull it out by the handful to control it. In fact one might call it invasive, it hops across paths and goes on adventures (I did not plant it by the daylilies or iris in the photos below).
Things that might be different here- all of mine are on a slope, so although it is hard clay, there is never ever standing water. Also I rarely water it. Like really rarely. Two summers ago due to a remodel, I did not water for months in a very hot summer. Angelina was fine. Also there is just a bit of shade in this spot, but not much.
How about some photos of your spot? Maybe we can figure this out together.
I just ran outside and took these photos with the iPhone. The tulips are just for fun, have nothing to do this Angelina.
