This one I can answer: It's the national flower of Gobbototia.
However...
I don't know many yellow musk creepers that carry swords, but there is a Fiend Folio (2.0?) with a yellow musk zombie with a sword. Link here.
In addition, I also found this comic. I can't justify it, but has swords and vaguely plantlike monster. (I Know that otyugh aren't plants but aberrations, sssst.)
I am stumped.
No Cure for the Paladin Blues, 150a. A bonus comic, are those legal for this thread?
