The Latin is Anemone blanda. A long time ago I got a little bag of bulbs for blue ones and I planted them carefully in the front yard. Some white ones came up, too.
Turns out you don't actually have to be careful. They're called windflowers because they self sow readily and the wind blows them all over the place.
The front yard is loaded with them now in light and dark shades of that blue I love so much.
They're exquisite.
The bees like them, too.
