An overview of recent results from LEP concerning the hadronisation process is presented. Emphasis is placed on the -quark. The first presented analysis is the measurement of the -quark fragmentation function. It includes a new, hadronic-model independent method to extract the x-dependence of the non-perturbative QCD component from the measured fragmentation function. This is followed by the results of two analyses on, respectively, production rates of b-excited states and branching fractions of b-quarks to neutral and charged b-hadrons. Multiplicity in the final state is also discussed concerning the difference in multiplicities between b and light quark initiated events, and total multiplicities in three jet events. Finally, recent measurements of \omega and \eta meson production rates are given.
