Seems to be the case I'll have to play the long game. They bring in this disgusting but shapeable soil to surround the foundation out here in central Texas. I remember growing up finding earthworms and fishing all the time, so they should be native.

The word you’re looking for is “naturalized”. Not native, but they’re already there, so...
If you have a new house, developments are horible, just enough soil to grow grass. You might be stuck buying good compost and soil and tilling that in deep, then letting grass grow for a few years before trying anything more.
