Mizulily sent me a tumblr post that said 'Person A owns a flower shop and person B comes storming in one day, slaps 20 bucks on the counter and says "How do I passive-aggressively say fuck you in flower?"' and suggested 'ok but Uryuu getting flowers for Ryuuken' so this was the result. She also wrote a continuation of this drabble, which you can find on her tumblr. For reference: orange lilies - hatred, foxglove - insincerity, meadowsweet - uselessness, geraniums - stupidity, and yellow carnations - you have disappointed me.
Passive Aggressive Floriography
by hashtagartistlife
"You want me to make a bouquet for Ishida-san," Orihime tips her head in confusion, "using orange lilies, foxglove, meadowsweet, and geraniums?"
"And yellow carnations," Ishida-kun interjects, slamming a $20 note onto her counter. "Don't forget those. Very important."
Orihime looks up at him. "Ishida-kun," she says gravely, "do you have any idea what these flowers mean?"
"I own several tomes on floriography, Inoue-san, rest assured I know what I'm doing."
Orihime twirls the note with his strange request on it in his lilting script between her fingers. "…. so what's the occasion?" she asks, while she resignedly pulls out a bunch of yellow carnations from her stock.
"It's Father's Day."
