Okay so I've kept careful track and this is what I've gathered
Orange is a girl, uses she/her, and presents androgynously
Yellow is a cowboy (gender-wise and also literally), uses he/him, presents mostly androgynously, and is also gay
Green is a chef (gender-wise and also literally), uses they/them, and presents androgynously
Aqua is Assigned Girl By Seth, Assigned Aqua By Seth, uses she/her, and presents femininely
Blue is a man, uses he/him, presents femininely, and is gay
Seth is questioning their gender, uses they/them (thank you @/capnportofficial!!), and presents androgynously
In conclusion, the seven human flowers are so Gender
(Also this propagates my theory that all utdr humans are born agender (only two human or human-esque characters so far actually associate with a specific gender (Blue and Orange (not counting Aqua because she was Assigned Girl By Seth))))
