The moduli space \overline{M} of stable genus zero curves with n marked points can be constructed as the closure of M{0,n} inside a toric variety. The fan of the toric variety is moduli space of phylogenetic trees. I will discuss joint work with Dustin Cartwright to construct other compactifications of M_{0,n} by varying the toric variety using variants of phylogenetic trees. These compactifications include many of the standard alternative compactifications of M_{0,n}.
