They look like a day lily or similar plant.
They are definitely not a grass.

At the site where an old house has been recently torn down and the groud
leveled, I found these
plants lying bare-root on the surface (surrounding them were some growing
from roots beneath the
ground. The roots start out long and narrow, but buldge out on the ends.
Is this a perinnial
flower that I should keep and plant, or just some type of grass that I can
toss?
