We demonstrate that exclusive B decays to P-wave charmonium factorize in thenon-relativistic limit provided that colour-octet contributions are taken intoaccount, and estimate the branching fractions. Although there are very largeuncertainties, we find reasonable parameter choices, where the main features ofthe data -- large corrections to (naive) factorization and suppression of thechi_{c2} and h_c final states -- are reproduced though the suppression ofchi_{c2} is not as strong as seen in the data. Our results also provide anexample, where an endpoint divergence in hard spectator-scattering factorizesand is absorbed into colour-octet operator matrix elements.
