I do think the Hunger Games has made in more useable, for me at least. I love most "rose" names but
Primrose was never my favourite. Since reading the books, I like it a lot more as I can imagine a real-life
Primrose, whereas before it always seemed too unusual to be used.
However, I don't think people would think you were a huge Hunger Games fan if you used it! It was a name before the books came out (unlike Katniss, Peeta etc.) and
Primrose isn't actually that main a character.
I like
Rose and
Rosie a lot, but also
Primrose as a full name. I don't like Prim though.
