Not sure what it is but it doesn’t look like Little Bluestem.

Did you feel the leaves? Is there any chance this could be a young Yucca flaccida?

^ I don't think so? They are thin and floppy, like some kind of grass or sedge?

^ Yes, someone else there IRL actually ID'd it as that (Blue-Eyed Grass/Sisyrinchium angustifolium), thanks!

Just to clarify the common name, it isn't actually a grass, despite the name. It's in the Iris family.

Yes, it's one of the few native, dry land Irises...like Prairie Iris (Nemastylis geminiflora)!

Of course, these are much smaller than the far more common Eurasian Irises, so not as recognizable as Irises.
