Horrible hot here and harvesting of crocuses goes in full speed with immediate replanting. Not easy, every afternoon almost killed by hot. And few new observations, not included in my coming book as I noted those features only few days ago, too late for correct manuscript.
This year I replanted my C. pelistericus too early - with still green leaves but new corms were well formed, but still roots active and I found that roots of C. pelistericus are well branched. Up to now it was observed only in C. vernus and veluchensis (see B. Mathew).
In one more species I observed stoloniferous habit - it is very well known C. speciosus. Plants collected on Tshatir-Dag Yaila in Crimea, Turkey formed in pots up to 7 cm long side and down growing stolones with small grain-corm at end.

I think you will find that Ian mentioned the branching roots of Crocus pelistericus some years ago in the Bulb Log, Janis..... I will try to find the link for you.
.... hmm, cannot find a link....it must be that Ian speaks of this in one of his Talks.... :)
There's this photo from Log 28 July 8th 2004 which show the root growth at repotting time and also, in the right hand side, the clearly branched roots.....

Does anybody know, whether Brian Mathew had living material of Crocus pelistericus for his monograph?
I guess he hadn't!
Thanks for your observations, Janis and Ian/Maggi.

In case some of you Crocunuts do not read the bulb log I will post these pictures of Crocus scharojanii flowering just now here as well.
To read what i say you will have to click on the link below.

Oh, Ian,
I'm so busy now in this horribly hot summer when it is possible to work only in very early hours ( I start with sun at 5 o'clock), that have no time to check forum and your bulb log. Even in my bulb shed in shade of 200 year old oaks temperature in day reach + 29 C. Tomorrow will be surpassed our all time temperature records for summer (by meteo-information), but in Finland it is snowing(!). Really I'm surprised that my scxharojanii regardless of very long shoots more than week ago still didn't bloom. Corms of autumn bloomers generally are of good size, not so well with spring blooming species. Hot came suddenly and just the hot is the agent stopping growing. I hear about very poor crop in Holland. Prices go up and a lot of crocuses, reticulata irises no more available.

I do not envy you that sort of heat Janis, I could not cope.
On the other hand our night time temperature had been dropping down to 4C and that is a bit cool for July.
Good luck with the replanting and harvest - I hope there are many successes.
-
Here are my first crocus for the season.
A yellow, tommo and what I have as purity which has quite marked streaking on the outside of the petals
-
Kees, 'Purity' was an old cultivar name for 'Miss Vain' but your plant looks different.
The true one doesn't have neither a yellow throat nor stripes.

Thomas, I just had a look at that thread again - what a stunning resource it is - and noticed for the first time your request for 'Myddelton Cream.' Have you been able to find it yet? If not, I could probably send you a corm or maybe 2 in the summer (my summer). I've only a very few but it's doing quite well and could spare something if that would help.
-
Hi Thomas, thanks for that. So do you have any ideas on what I have, it is quite a small flower and quite pointy. I like it quite a lot.
That really is an excellent tool, thanks
-
Thanks for your offer, Lesley. No, so far I don't have a plant of 'Myddelton Cream' although I had two offers.
If yours are dormant you could contact me again and ask if some arrived here?
Kees, from your photos it's hard to identify your plant. Could you post a photo of the outside of the petals?
But I think that's not a registered Dutch cultivar - probably one that originated in OZ or NZ?
-
Surprise from the postman: 2 small corms of Crocus chrysanthus 'Myddelton Cream'
arrived in Neustadt this morning together with other rare chrysanthus cultivars.
-
What were the others Thomas? :)
-
Warley
Gündogmus Bronce
Aubade
Snow Crystal :D :D
-
Hi Thomas here are the pics for you, any help with an ID would be great.
-
Kees, the markings look like 'Snowbunting' but your flowers don't have the
yellowish groundcolour of typical 'Snowbunting'. I guess they aren't a registered
Dutch cultivar (at least none I know), but nevertheless they are beauties!
-
Warm and sunny today 15c (winter was a non event :)), and a number of crocus are are just starting to shine.
Crocus chryanthus snow bunting.
C.chryanthus zwanenburg bronze.
C. gargaricus in a very shady trough.
A couple of plants i should know the name of --umm .... :-\
Finally first flowering of C.abantensis --a lovely little thing --Label says seed x Gothenburg Bot.Garden sown march 07---however most of the plants in the pot are very small non flowering seedlings -- i remember Lesley C. giving me a bulb or two a number of years back which i cannot locate --- maybe i have combined the two pots ,(as sometimes i'm inclined to do). :-\ :-\
Cheers Dave.

Crocus abantensis blooms from very small corms and it is one of very few species which is far better growing in open garden where form much larger corms. In greenhouse it is too hot for this species. I prefair to grow it in garden, although it is something risky as once I lost it during black frost in winter.

Thank you for that info Janis.
Planted out in the garden they will go then --i have far too many pots anyway ;D--( sigh ! despite a recent makeover i fear the garden is quickly filling up again :-\).
Cheers Dave
-
Dave I think your purply one with the yellow base is sieberi, probably 'Firefly' or 'Violet Queen' I'm not sure what the difference is between these two. Not sure about the gargaricus either. Isn't that plain yellow? I would have thought Chrys 'Fusco-tinctus' maybe. For years (and still) everything coming in from Holland as 'Zwanenburg Bronze' was 'Fusco-tinctus.' Took me years to find the true form again, with the solid bronze flushing after losing my original van Tubergen imports from 40 years ago.
-
Not sure about the gargaricus either. Isn't that plain yellow?
Oops ::)
Thanks for pointing that out Lesley .
Here is a pic ,(which i omitted earlier), of C.gargaricus in a shady trough .
Cheers Dave

Dave,
lovely crocus pictures. Particular like yor last image.
-
My crocus look identical to yours Dave. So snow bunting it will be from now on.

Sorry for my late reply, havn't been online for weeks now.
Kees, please compare your plant with this photos of the true 'Snowbunting':
http://www.srgc.org.uk/smf/index.php?topic=5060.msg138199#new
You will find, that yours is different to 'Snowbunting'
