CB+petals+free

If you look closely at a flower, you will realize that it is surrounded in petals, acting like a shield or barrier to it's precious insides. The author uses the image of being free of petals, or in other words, free of the barrier holding her back from doing the things that she wants to do. It is now very clear that the author is talking about braking that boundary, and not holding back from the things that make life wonderful.
