We investigate elastic interactions in nematic elastomers and gels using a Ginzburg-Landau model for the isotropic-nematic transition. We propose an elastic origin of the "four-leaf clover" pattern observed in depolarised light scattering from polydomain nematic elastomers. We also investigate the director fluctuation in the nematic phase. Aligned nematic states are found to be unstable below a critical elongation.
