All I can learn from a quick google is that it's a short-lived perennial, which self-seeds freely. You can probably plant it at any time, but self-seeding would effectively be autumn planting. Try about September-ish, and if it doesn't come up straight away, it probably will next spring. With so many Eryngiums about, I bet it's an easy one you can plant almost any time.

i bought the World Classics or something like that from Wilko's this Spring for 'miss wilmott's ghost' and sown them indoors in March time I think,  but they didn't germinate for me at all despite putting them in a heated propagator and i waited and waited. I think it takes upto 60 days or something for them to come up but nothing did..  my compost was either a newly sieved HM, microwaved compost or newly sieved MP compost... has anyone grown this before, if so where did I go wrong?

Maybe you should have chucked them out in the cold for a while. lots of perannuals need winter

I bought the same from Wilkinsons and mine didn't germinate. I might just scatter the seed somewhere in September and hope

I have a lovely Eryngium plant and have been trying to grow new plants by saving the seed and sowing in pots but it never grows, however it freely self seeds itself into cracks between paving stones!  I left two plants this year which weren't too much in the way, and they are in full flower and beautiful

So i suppose plant would be better the let them self seed
