“Ellen is caught in frigid New York but we can feel her evil presence from the video,” joked Rob Sharenow, EVP and General Manager of Lifetime, as he introduced the Flowers panel, after announcing the sequel, Petals On The Wind.

Flowers is set in the 1950s, as is the book because in this era of Facebook and Twitter, “you can’t just have two teens disappearing without people knowing where they are,” said screenwriter Kayla Alpert. Much discussion during the Q&A session as to who on the show’s cast and in the audience had read the book as children — what with it’s  incest, mother abandonment, kids stuck in the attack, evil Granny, etc. “I do want to confess I did read the book —  above the covers because my parents took no interest in what I was reading,” Sharenow said.
