I'm still somewhat confused about how far one can go in naming some primulas, Susan.
Primroses and cowslips hybridize in nature and there's been all sorts of artificial hybridizing between these and various other primulas for a long time.
Still, find several different types of Primula very reliable here; notably drumstick primulas (Primula denticulata) and especially Japanese primulas (P. japonica).
I particularly like the latter, especially 'Miller's Crimson'. Find it reseeds in our garden (quite gently) and it's easy to move the rosettes.
Perhaps it's to do with the way we garden as well as to do with our growing conditions.
Will post pictures as they bloom.
I'll name a few other primulas as well.
I've usually had the information from the plant labels at the time of purchase and, from past experience of naming animals, I'm kind of locked into plant nomenclature.
Commercial interests really confuse things, sometimes perhaps to the level of unknowability.
Not wise to be too perfectionist about such things!
