It's cute. I don't think it's too associated with The Hunger Games. First of all the series has kind of disappeared (it didn't have staying power like
Percy Jackson or
Harry Potter) and second of all it fits in with those British garden names (
Lily,
Violet,
Daisy,
Poppy) so it's fine.
I like it but I dislike Prim and Primmy by themselves. I wouldn't use any nickname but if I had to
Rose (I like
Rose but if you were to call her that you might as well name her
Rose).
