Coming from another language (which was why I know it under the name "ruccola"), I had no idea what that referred to and even missed that it was a reference to anything and thought he just picked some random word xD
But googling I get loads of results, including wikipedia explaining that it's supposedly the same plant, one being "commonwealth english", and the other american? and fun fact, apparently the name
"rocket" derives from the Italian word "ruchetta" or "[B]rucola[/B]"
, which in turn is apparently a diminutive from the lating name ("eruca").
(and no, I'm not italian)
TIL
Didn't manage to find any references to why rocket is considered an inferior name, though? Would love any explanations regarding that rivalry (or if it's a meme or whatever).
ps: @elan, already mentioned it higher up, but salad and lettuce are homonyms/synonyms. Somewhat unsure if that holds true in english too (google does
suggest so at least (ie. "
salad greens"), which is why I keep using it. But few 'official' dictionaries confirm, particularly if I
remove(#2) the word 'green'), but it does in a fair number of languages at least.
