Storing cyclamen seeds

Hi Diane,

I occasionally get my own purpurascens seeds, but not many or often.  Most
of my plants are in the garden.  Seeds have also come from a variety of
sources in Europe - Jan Bravenboer especially, also the CS and a couple of
good friends who know their cyclamen very well and how to take care of
seeds.  I don't see much difference between them, other than some batches of
CS purpurascens seed never germinate at all.  You have hit the nail on the
head - however controlled your experiments are, it is impossible to control
what happened before you got the seed and this may be a major factor
impacting your results.

Seed set on many species has been pretty good this last season and some,
like intaminatum under glass, are already ripe.

John reports no difference in germination time for all his cyclamen  
species, including purpurascens, and I wonder whether he is sowing his  
own purpurascens seeds and has developed a strain that germinates  

My Cyclamen Society purpurascens seeds sown in mid-October under the  
four different conditions  germinated from November 8 to January 9.

The CS seeds from all the donors are put together, so it is difficult  
to know how they have been treated prior to my receiving them.

  I have not had any seeds from my own plants, so haven't been able to  
germinate fresh seeds.  Christopher Grey-Wilson wrote that  
purpurascens does not set seeds readily, particularly if grown in  
pots.  Do you get many seeds, John?
