I think that's it. I have one in my own garden but I can never remember the names of my own flowers. Thank you.

Sounds familiar....

Allium cristophii?

No, not christophii. Utterly different.

Allium stellata, prairie onion. They are common and blooming now. The Allium cernuum, nodding onions finished blooming earlier. Allium stellatum actually oops. I'm growing them as garden flowers. They have adapted to growing within the prairie grasses.
