Crocus August, 2018

[Yann]

interesting to see how you manage your labels Janis.  Very clean nursery!

[Tony Willis]

Janis thank you for showing the picture of the corms with Fusarium dry rot. This is something I have very often and have not been able to identify the problem. Do you have any idea how the problem arises and any preventative measures

Surprised that regardless of long shoots at repotting time still no one autumn crocus are blooming.

I observed last year that a shoot came out, when it was rather warm. Nothing happened for a week or more. Then the temperatures dropped and within one or two days the shoot grew on and flowered.
At the moment I have a single shoot out but as last year it is still too warm for it to flower.

Here is my first flower this season: Crocus mazziaricus aff. from Samos. Unfortunately it needs some sun to open.

Very nice - when will come up mine?

Very nice - when will come up mine?

Hopefully soon!
We look forward seeing all your beautiful Crocus.

By me the second flowering  one in an uncovered frame is Crocus scharojanii flavus.

It looks really nice!

Hallo Steve, this are wonderful crocus-fotos and the beginn of the new saison seems to be very early, here in germany after a very hot and dry summer the colchicum started 3 weeks earlier too!

[Tony Willis]

Steve beautiful pictures of lovely crocuses. No sign of anything showing here yet

[Yann]

nor here, and indeed great shots.

Crocus karduchorum ex SASA-102

Steve, your Crocus karduchorum looks more like C.cappadocius. Think karduchorum have other styles. Here my Crocus karduchorum.

Thanks Dirk.

I bought this from Janis Ruksans as “Crocus karduchorum ex SASA -102”.
Perhaps Janis may be able to comment on this plant.

[Janis Ruksans]

The plants SASA-102 were collected by Archibald, Stevens, Seisums at pass on old rd to Hizan from Van where only C. karduchorum is growing. They were very variable as you can see on attached picture - all grown in same pot from same gathering. All my C. cappadocicus comes from much more Western locations - Doģansekir and Ziyaretpesi gec. near border between Kayseri and Sivas Provinces and they has distinctly yellow stigmatic branches. I never saw plants of cappadocicus reported from Erzincan and Tunceli, but even they both are located more to W from SW corner of Lake Van from where C. karduchorum is described.

I'm separating both species +/- surely just by colour of stigmatic branches. Seedlings of karduchorum having yellow stigmas are discarded as occasional hybrids, but some has slightly creamy stigmatic branches as between original plants. Actually as most typical I regard only those with pure white stigmas, but how constant it is in nature - I don't know. I never was there at blooming time of karduchorum.

[Janis Ruksans]

The Crocus kotschyanus group is very complicated - plants from type localities are more or less identical and easy to identify, but there are very few data foundable at their blooming culmination in wild to see the complete variability of them and distribution area of each of them. Crocus cappadocicus is registered from two general localities, but in cultivation I found only plants collected near Ziyaretpesi gecidi - the most W and S located population, I saw them only in spring, never succeed to be there at blooming time, so all my judgments about variability comes from few plants collected by me and many more bought from other growers/collectors. On the map it is marked red.
Another 2 localities is positioned more to East and North - from there no one plant was seen by me. On map marked yellow.
The plant pictured by Kees Jan still more to North and most likely representing new species is marked on map with green.
The karduchorum locality - has brown mark.
I must note that at green and brown points only few plants were seen by Kees Jan in 2011, so no information about variability in wild.
But there are still more "enigmas" - what is suworovianus lilacinus? What is kotschyanus from very South (Syria)? Distribution area of hakkariensis?
