But...hmmm...it's true that cohesion with other boards is important, but I feel like it makes more sense to use the recognizable name of the flower (the way they are on the game's Wiki).

I feel the average user would be able to understand "Easter Cactus" better than "Hoshikujaku". Since they're flower girls, you'd instantly know what flower they were from the tag.
Didn't understand it like that, though the girls had a name, and a flower name.
Still, the english name is far better than the japanese.
