[1] The film relates simultaneously the lives and romantic/sexual relationships of the Petunias: the parents, Felicia and Percy, and their three sons, Michael, Adrian and Charlie.

The film also features the wife of Michael, Vivian, and her cousin George.

Due to its very limited release,[1] the film has been reviewed by few outlets.

Frank Scheck from The Hollywood Reporter weighs, in a lukewarm review, a "wildly inconsistent" plot against "some marvelous moments and a terrific ensemble".

[2] Dennis Harvey in Variety compares the film to director Todd Solondz's works, judging Petunia to have "a bit less bile (and punch)".
