The production of b hadrons in e⁺e^- interactions at the Z pole allows to perform detailed studies of their properties. Almost a million of Z⁰\rightarrow {b}\bar {{b}} decays have been detected by the four LEP collaborations. In this contribution, some recent results on heavy flavour physics are presented.
