Another fun fact about plant naming conventions: all lettuces* are the same species
*except wild lettuce but nobody really considers that a lettuce. Still, I guess it would be more correct to say all of the food lettuces are the same species.
Irrelevant side quest that I went on while double checking this: DuckDuckGo now forwards some search queries to their chatGPT wrapper, which prompted (pun intended) the following interaction:
Are those actually considered lettuces, though? It’s most likely a cultural thing but none of those are lettuces over here. As in, calling them lettuce would be as far fetched as calling spinach lettuce.
