lycoris sanguinea

L. sanguinea has come and gone. I did not recognize it when it came up, not
having seen it before. I don't think anybody grows it here in the Chicago
area, except maybe at the botanic garden. Boyce?. Not the big trick will
be to see if it continues. It had no mulch last year, so will do exactly
the same thing this year.

The Wiki confirmed my best guess as to its identity. The color,
conformation and shorter anthers nail it down.
