Due to its large acceptance, the STAR experiment has acquired a wealth of data on strangeness production for a variety of collisions systems and energies, from p+p to Au+Au. By using the yields and spectra, we address the evolution of the bulk system, including strangeness enhancement and the flavour dependence of radial and elliptic flow. Utilizing the fact that we can identify strange baryons and mesons, we investigate different hadronization mechanisms in the intermediate and high-pTregions. The ratios of the particle yields, measured to high-pT, are used to further investigate the range and applicability of the previously reported anomalous baryon production. We also study two-particle azimuthal correlations of identified particles in order to investigate any flavour dependence of jet fragmentation in the available pTrange. Data are presented for a number of different collision systems and energies.
