In The Garden: Very invasive weed? - hosta look alike

These started to pop up in our garden beds and lawn about three years ago.
They first appear mid-May, green leaves are very tightly curled around the stem before opening. Height approximately 10". Very hard to remove - stem breaks and roots remain. Basically need to be dug up.

Any idea what these are and how to get rid of them?

Thanks!

 

Are you sure that's not a desirable?
Would love to see pictures of it after it flowers.
