Primula polyneura (or a plant grown with that name) flowered earlier in June.
Also Primula waltonii started to flower already in June 10 and is still flowering. It has a peculiar flower stem this year.
This orange primula was grown from Insriach hybrids seeds, and it is flowering right now. Is is P.x bullesiaana?
The last one is grown as P.burmanica, I was expecting a redder flower but it is a late flowering and is now starting to grow second round of flowers so it is only in the beginning of flowering.
