Right on. Although, I grew up saying peecahn. Not that we have any up here.
Most of our population is Norwegian stock. I have never heard of wild greens being regularly gathered in the past, although some older folks talk about eating dandelions and young nettles and milkweed flower buds in the Spring, plus baby ferns, still curled, although few use the term *fiddleheads*. Up here everything is *pop*.
I love the way vocabulary changes in different areas. When I moved to Milwaukee in the 60’s, it took me awhile to figure out that *bubbler* was a water fountain.
Here’s another fun list of what words people use for the same thing.
