It had been suggested the above was actually a Cortusa.
A 'P.jesoana' from an AGS show did actually turn out to be a Cortusa when it flowered earlier in the year.
I compare the 2 plants together, along with a Cortusa photo from the web.
The Cortusa is more 'star' like, the Primula 'bell' lke. I'm convinced even if you're not!
