Which of Ahrends' "Schnee" cultivars of Primula × pruhoniciana are SRGC members growing, or which they know to be available in the trade?
I haven't mounted an intensive search for information on these, but it appears that most of them are no longer available.'
PS: I forgot to add that I have two of these, 'Schneesturm' (Snowstorm) and 'Schneetreiben' (Snowdrift). Some very odd and unexpected plants turn up from time to time in our local garden centers!
