I have similar flowers in my side garden, that come up every year. Let me know what you find out!
Looks like a variety of blue-eyed grass to me, which is often a native perennial grass and very low maintenance. Does that seem right based on what the petals look like up close?
Looks a bit lighter than I originally thought - so I'm betting it's Glory of the Snow which comes up very early in spring (hence it's name!). It's a low maintenance ground cover - and gives your garden some color early.
Looks like that's it, thanks!
