Could you explain your question? You've shown a picture of mint, referenced oregano in the heading, and asked about "Ireland". I can't find any listing of mint or oregano by that name, so I'm stumped.

Please post in the Ask A Question forum, found at the bottom header, instead of adding an unrelated post to a photo of this mint. Once you so so, I will delete this thread.
