I had a customer come into my garden center today and ask for “those mini sweet peppers. you know, the ones grocery stores sell”. I have no idea what those peppers are. I suggested a sweet pimento, but they wanted the grocery store was selling.
I linked to what I think the person was talking about.
Maybe it’s a gypsy pepper.
