Good call Nick! It is Oenothera laciniata, Ragged Evening Primrose, a common native plant of bare sandy soil. These leaves seem a bit too large, but basal leaves often are noticeably different, and so are winter leaves. On a side note, I have never even thought about tasting this plant! What does it taste like?
Exploring the dune country of Lake County, Indiana last weekend, I was surprised at the many subtle colors in the winter leaves of this plant.
