Right, the picture. The height of the entire thing is only about 4 inches.

dunno, but it's cute!

I hope someone knows what it is;

if it's anything non-harmful, I'd like a start!

It's miniscule Sylvia, but you can have all you want. It must reseed like crazy because I don't remember seeing it last year but it is all over the yard today when I mowed. But then I didn't have that rotten vetch last year either and it is everywhere this year.

I believe it's blue-eyed grass, a cute little native, and it's in the iris family. Mine is much bluer than this though.

Blue-eyed grass

No, not blue eyed grass. I have that too. This is smaller.

There are quite a few species of blue-eyed grass in Texas. Some are quite tiny and some much larger. The flower may open a bit more in a day or two. Perhaps it is white blue-eyed grass, Sisyrinchium albidum. See if there is a little 'tooth' at the end of the petals.

Lin and Eric are both right. That link helped a lot Eric, thank you. I mowed most of them down but found one that I missed and potted it for you Sylvia. But I warn you, the bloom is only about 1/8 inch in diameter. If Eric hadn't linked to a picture I wouldn't have noticed that there is a point on the end of the petals. Where it is growing in my yard (thin soil on top of rock), it it at most 4 inches tall, not the 8-15 inches it says on that link. Maybe with better soil, it would get bigger.
