From Argentina comes what is perhaps the king of eryngiums. This statuesque plant, which has evergreen, toothed, sword-like rich green leaves is in fact very hardy, whilst having a tender, exotic tropical look with massed heads of large grey-green spiky flower heads.
Sow seeds IMMEDIATELY you receive them, at any time of the year, they depend on having several months, sometimes up to a year 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 and do not discard. These fresh seeds can be very slow to germinate but do not use any artificial heat in an attempt to germinate them as it may simply disrupt their germination mechanism causing them to enter even deeper dormancy.
