Sow seeds IMMEDIATELY you receive them, at any time of the year, they depend on having several months in cold, damp compost, (NOT DRY IN A FRIDGE) before they will germinate. Keep the seed tray moist in a cold greenhouse or shady corner. These fresh seeds can be very slow to germinate. Do not use any artificial heat in an attempt to germinate them as it may cause them to enter even deeper dormancy.
