Here's the wiki, if you're interested.
These grow in a big patch by the side of the road and this year they are truly spectacular. They're an unusually pale blue variety. Most are a nice medium blue. These almost look white.
They usually bloom right after the daffs finish. I look forward to them every year. If you look closely at the leaves on the ground in this pic, you can see that there's a little twinleaf and bloodroot there, too.
Such treasures. By the side of the road.
