Looks like variegated liriope. So neither a grass nor a sedge :-)

Thanks for the suggestion! Definitely not liriope. I love that stuff, and have quite a bit of the variegated sort. I agree the pics look sort of like it. I’ll try to get better ones tomorrow.

This “grass” is much finer. You know how liriope has almost a leathery texture? These blades are papery thin. And only about 1/4” wide, if that.

The roots are hairy and fine, not at all like the wiry orange roots of liriope. Pulling apart a clump is easy-peasy. It almost falls apart. Vs the “I need wire cutters to divide” liriope. This “grass” doesn’t form the thick, fleshy root chunk that liriope does.

lol. sorry to harp on the differences. That just gave me an excellent comparison point to describe it. Thanks :)

Compare to carex "Ice Dance"; looks similar.

That is not 'Ice Dance'. That is much taller than 4-6", has wider (1/2") and quite fleshy, stiff leaves and the variegation is very pronunced - solid green with narrow white margins.

My first thought was also that of carex.
