  We study the recently observed graphene fractional quantum Hall state at a
filling factor $\nu_G=1/3$ using a four-component trial wave function and exact
diagonalization calculations. Although it is adiabatically connected to a 1/3
Laughlin state in the upper spin branch, with SU(2) valley-isospin
ferromagnetic ordering and a completely filled lower spin branch, it reveals
physical properties beyond such a state that is the natural ground state for a
large Zeeman effect. Most saliently, it possesses at experimentally relevant
values of the Zeeman gap low-energy spin-flip excitations that may be unveiled
in inelastic light-scattering experiments.
