A meromorphic projective structure on a punctured Riemann surface X�P is determined, after fixing a standard projective structure on X, by a meromorphic quadratic differential with poles of order three or more at each puncture in P. In this article we prove the analogue of Thurston's grafting theorem for such meromorphic projective structures, that involves grafting crowned hyperbolic surfaces. This also provides a grafting description for projective structures on C that have polynomial Schwarzian derivatives. As an application of our main result, we prove the analogue of a result of Hejhal, namely, we show that the monodromy map to the decorated character variety (in the sense of Fock-Goncharov) is a local homeomorphism. © 2021 Elsevier Inc.
