Hi Arturo, I grow this one outdoors. It doesn't need to be in a pot, but like many Himalayans it needs a lot of moisture in the growing season which is easier to provide in a pot. I would put it in the 'wet meadow' category of Primulas but I have grown it in normal garden conditions. It doesn't seem fussy about pH.
This year I have given it a splash of fertilizer which it seems to have appreciated, and the wet cold spring also makes good Primula conditions.
On the whole this seems to be one of the easier Himalayan species, though it does have a tendency to be short-lived so collect seed. It doesn't seem to mind winter wet but it won't like summer heat and drought I expect.
I think this could be harder for you to grow than for me, but definitely worth a try. Seed is often available in the exchanges and I'll be donating some of my crop.
Regards, Tristan
