I don’t recall ever seeing this blossom before. The plant of which it is part is pleasant enough in appearance and would be an asset to any garden, even when not in bloom. If the plant is native to Virginia (I am partial to indigenous species), I would love to have it in my garden.
Update: That didn’t take long. LarryG identified the flowers as bluebells, a common flower. I guess I don’t get out enough.
Update: Turns out that there is an annual Bluebell Festival in Merrimac Farm in Prince William County! That’s coming up in one week.
