Mystery Plant

While hauling weeds from the garden a couple days ago, I discovered a few plants I had not seen before. They look like they're in the orchid family. The flowers are small, and are shades of pink and yellow. They are growing beside the driveway in a shady location.

If you have any ideas about these sweet little flowers, please leave me a comment. Thanks!

Many thanks to my friend Jane for identifying this lovely little plant as Helleborine! Sure hope it comes back this spring.
