In Oresuki, the anime about meta-4th-walling romantic polygonal turned actual plot, the characters all have nicknames from different flowers. The flowery names take on literary significance both as summaries of the character concepts respectively, but also for fun and jokes. There is also a flower language layer in which is both in-universe and in interpreting the theme.
What I really want to talk about is Japan and its view of the Dandelion, or Tanpopo. This flower gets romanticized a lot in Japanese films and TV, as well as anime, games and manga. But as an American I just cannot bring myself to like it.
It is a bit like how a hardcore terran marine cannot quite bring him or herself to like zerglings. You dehumanize them. You fight them all of your life. You know they are worthless weeds, literally. You don’t even really think about it other than annual chores that took up countless hours since your childhood, eliminating it from the places that you call home. Or if you own one, also the time (and money) spent dealing with the plant pest. Sure, it’s neat that the plant propagates by airlifting its seeds. Sure, it is a hardy species in which can survive in all kinds of temperature zones. You can even eat its flowers, or make it into tea or whatever (I don’t recommend this in North America, just because of residential and commercial herbicide in use).
Which is to say I was delighted to see a character named Tanpopo in this anime, being literally the stupidest thing alive, being sidelined by the main characters. Unlike most depiction of tanpopo in JP media, this one is a lampoon of such. It isn’t her fault and her intentions may be acceptable, but Tanpopo is a nuisance.
