I wonder if the early deaths are down to genetic or environmental factors..........

Chris

I think it is genetic, C. persicum can live easily to 20-30 years and more, I have seen tubers in the size of a big plate.
Probably the albidum form are genetically short lived.

Sounds like it's genetic then, I wonder if other albidum cultivars are short lived, maybe a feature of the albinism, or if it's just a 'random' feature!?

Albinos of almost everything have a reputation for being weaker than non-albinos.

The Cyclamen coum here have been trying to flower the last month, but are being interupted by our current cycle of snow and thaw. They seem to be coping well with the temperature range of minus15C to plus20C.

Hi Kris, amazing how quickly they bounce back into life. Ours are frozen to the ground again today with -4C  ::)

I agree Simon ,but I  see  that the ones from  the sunny rockgarden (between rocks) better recover then the ones  from the flatground in a richer and shadier border...

Could that be due to a difference in growth form, Kris? The ones we have in sunny, or rocky, areas in the garden produce leaves with shorter stalks than those in the woodland. So they do not seem to be pushed down onto the soil as much. How do yours compare?

Yes Simon, I had  not immediately an  explanation for this observation but when I start to analyse your quote I find the same circumstances in my garden.So you must be definitively right .... :)

 ;) Both growth forms have their merits- but I do prefer C.coum in rock work in the garden- though it is more normal here to see them wild in the woods.

In the October 1974 issue of the American Rock Garden Society Bulletin, Vladimir Vasak of Prague published a short paper "Cyclamen in Colchida". In this paper he mentions the follow taxa in Cyclamen

  • C. abschasicum (Medw.) Kolak.
  • C. adscharicum Pobed.
  • C. calcareum Kolak.
  • C. circassicum Pobed.
  • C. coum (Mill.)
  • C. ponticum (N. Alb.) Pobed
  • C. vernum Sw.

In the last 35+ years, Cyclamen taxonomy and nomenclature has undergone considerable changes, and of these taxa, only Cyclamen coum is recognized. (Astute cyclamen lovers will note the absence of Cyclamen colchicum from this list, but it's merely shy, hiding under the name C. ponticum.)

Vasak gives locations for these taxa, but locating them on the map isn't easy. After some fairly serious digging around online, I've pinpointed most of these locales and present them here for anyone wishing to look into these matters.

Roger,

more info than I need at the moemnt, but I'm really happy you researched this.  Thanks ever so much!  Cyclamen are going to play an important role in my new rockery and understanding where some of these variants grow, well, it just helps a great deal, doesn't it!

Do you know if the Czech article is available on-line somehwere?  I would love to read it.
