You may have hit the jackpot.
Those are Daylily (Hemerocallis) plants. There are many fine flowered
Daylily cultivars out there.

Plant them and see what the flowers look like.
If you don't like them, you can always dig them up and discard them later.

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?
