Actually it's Iphion uniflorum, aka Spring Starflower.

I have masses of them in my own garden.

From the pictures I think it is more likely Ornithogalum umbellatum
(Star of Bethlehem) which I have in several places in my yard. Hard
to know without a closer view, but the way the flowers close and the
way the flowers come off the stem in the second picture really makes
me think that is what it is.
