Here it advances very slowly, the last nights were always under zero.
Only some new flowers today:
Crocus kotschyanus ssp.kotschyanus f. leucopharynx pale form with
the 'normal' form from this species
Crocus speciosus ssp. xantholaimos
Crocus serotinus ssp.salzmannii

Two views of Crocus mathewii
Very beautiful Tony. Your own collection I presume?
-
I found a HUGE C. nudiflorus in the garden today - twice the usual size and producing two flowers from one corm. I have hundreds flowering and can't see another with two flowers to a corm, and can't remember ever seeing this before. I'd be interested to know if anyone has seen nudiflorus producing more than one flower to a corm?

I agree with Luc and Gerry ....Tony's form of mathewii is FANTASTIC !
-
Tony, that is a perfect mathewii in my opinion!
Dirk, a lovely dark banaticus and an interesting cross!
Crocus speciosus albus
Crocus vallicola looks great now, and there are some welcome variations.
Yesterday Crocus wattiorum opened its flowers.

I've lifted and potted my extra-large C. nudiflorus to grow on and see if it continues to produce huge flowers and two flowers to a corm in future years. Since no-one has commented to say that they've seen nudiflorus producing two flowers to a corm, I'm assuming I was right in thinking this was unusual. Matthew describes it as having solitary flowers. Hope the twin-flowered characteristic proves stable.

Thank you for the remarks about the Crocus mathewii. No sign of Crocus wattiorum yet but this Crocus nerimaniae has appeared.
-
Lots of lovely crocuses on this thread. Sunshine at the weekend saw my own crocus looking mighty fine. I'll not repeat what so many have already shown ..... jealous of wattiorum and nerimanae that I do not grow.
Here are a couple of images from the recent display here. First a very nice form of Crocus goulimyi var leucanthus with a 'normal' goulimyi beyond. The other just amused me, spot the spider waiting for pollinators in this pulchellus x speciosus :)
-
Great images and species from everybody.
3 days rainfall and night temperatures down to 5°C induced growth.
My first autuum crocus are seedlings of C. pulchellus 'Zephyr'. More noses are visible...

I'm quite happy some 'strong' survived the black frosts from 2012.

No spider in the flower - only a potential pollinator! :)

Sorry, but it is Crocus suworovianus.
Janis
Why?
-
This crocus which came as Crocus sativus 'Cashmerianus' is blooming in my garden this past weekend.
this form looks so much like the Dream Dancer mathewii but for the white outer tepals.
is the one in the second pictured virused?

Why?
Tips of petals. Compare with another picture of vallicola one or two enrtries later. Sometimes not easy to separate, but this one definitely loks as suworovianus.

Returning to Crocus vallicola. Today I pictured some of them. Most interesting are two pictures of cv. 'Blushing Marmot' selected by Henrik Zetterlund. When it started (5 days ago) I was afraid that I got wrong corms but today they got characteristic colour. Note tips of petals. Last picture are seedlings - comercial stock.
Janis

Now three pictures of Crocus wattiorum and
Crocus nerimaniae - they are seedlings of 2nd generation and it seem that finally my stock is clean from virus infection.
As last in this entry - Crocus banaticus

Now two gatherings of Crocus laevigatus subsp. pumilus from Crete and type laevigatus from mainland Greece.
After that my traditional stock of Crocus oreocreticus and seedlings of C. oreocreticus grown up from seeds collected in Crete (near cave of Zeus) by Marcus Harvey (Australia) and kindly shared witjh me - note variability.

:o Wow , fantastic C. wattiorum Eberhard . You keep it frostfree ?
Kris, this is not my merit. Crocus wattiorum is a new acquisition by Janis. I was amazed and delighted at the strong bulbs. Frost-free I can not overwinter here. Although I have read that this Crocus should be something sensitive to frost, but I hope it survives the winter in an unheated glasshouse well.

Hi Poul,
very nice crocus.
is the "Snowdrift" much larger than the type banaticus?
what are the green pellets on top of your pots?
-
Different Crocus speciosus from my garden and greenhouse
Hi Poul,
you have a lovely crocus collection. I like your C. banaticus seedlings and the C. kotschyanus HKEP9205. The latter is a very nice form, larger in growth then many commercial forms and has a lovely light purple colour. It is a pity I've lost mine by black frosts.
No. 2. C. speciosus Albus -> looks more a C. pulchellus albus ;)

Thank you all for the nice comments!
Rimmer, the Snowdrift is the same size as the average blue banaticus. However a few of my blue seedlings are almost of double size. The green pellets are slug pellets.

Hi Armin,
If you remind next spring I will send you some offsets of HKEP.9205.
C. Speciosus Albus is a new one to me, it is from a commercial supplier, so you might be right.
I was suspicious myself, it does not have the same characteristics as speciosus, and opens in a different way.

I love crocus, too! Ok I'll start my first official post (second really because the first was a seed request) with my little crocus which have been blooming for a week. I lost the label to the wind since last year so I'm not sure what they are, could you help me there too? I might have planted ligusticus around there but it looks different to me...

Very nice Ian. It's flowering here too for the first time, from a Jan 2010 sowing (RRW 09-175 via JJA).
Several flowers have appeared sporadically over the last month or so rather than together, but I've been tickling them in hope of a seed set.
-

Thanks Tony and Yes it was quick I also sowed in 2011 as well and there are seedlings from that sowing too but I didn't expect a flower yet. Nice mathewii but they are not showing here yet and it certainly hasn't been a success story with me so far.

I have similar ones in my garden, but I have never seen them eat crocus, only other small plants, mostly in my vegetable garden. I do not hope that they get taste for crocus or other bulbs!

Great images from all!
Autuum season no. 2 after Feb. 2012 black frost desaster:
Counted some 25+ survivors (C. specious and hybrids with C. pulchellus 'Zephyr') :)
All other autuum species disappeared :(
Interesting findings:
1) not a single crocus flower to find in my raised beds. All original stocks seem eradicted.
2) all crocus flowers in the meadow appear close to the stone wall (stones gave a protection?)
3) all are invaryable escapees (seed) from the original stocks in the raised beds
4) Ants have probably done a good job! :D
I'm excited how it develops the next years...

Crocus goulimyi is in full glory today
Glorious indeed.
I think that the first pic, of a group, is the only one that is goulimyi though. The others look like nice forms of Crocus niveus.

i did question the lack of the goblet form on the white and other single one, so i agree
You are correct! my mistake i get these names mixed up. the posting is my way to straighten them out.
Boy you are good at this!

And finally Crocus tournefortii - or is it a hybrid?
Poul
-
Hi Poul
this the my Crocus tournefortii from PC blooming a few weeks ago.
yesterday i noticed some shoots on Crocus tournefortii that seemed stalled in growth so gave a little pull and they dislodged as if the base was rotten.
is this problem due to too much moisture or inconsistent moisture after being covered and baked all summer?
We have had a lot of rain recently and these are in an open frame.
i have had this problem of stems aborting before with other fall crocus coming into bloom after heavy rain.
-
Rimmer
I have had this problem with some autumn flowering galanthus and on tipping them out I have clearly over watered and the roots have rotted as well as the flower stem aborting.
-
Thanks Tony
would you recommend that Crocus tournefortii be planted in the open garden side in a sand bed or well drained clay soil to use the earth to wick away the excess moisture from fall rains? or use a smaller pot? This was in a 16 per flat size pot (~2/1/2"), i use 32s (~2" pot) for seedlings.
though we has a lot of rain and the pots in the sand plunge were quite damp, the undisturbed soil (clay) in the open garden is rather dry, but the disturbed garden soil is very wet. I think the undisturbed soil texture is very important for drainage. but fall planted bulbs result in disturbed soil that absorbs too much water, then heaves in the winter freeze thaw cycles.

I have similar ones in my garden, but I have never seen them eat crocus, only other small plants, mostly in my vegetable garden. I do not hope that they get taste for crocus or other bulbs!
Poul
These are earth caterpillars, larva of night butterflies.
They eat only the stem and, besides, pull the blossom in the earth. The corm is not damaged.
This year there seem to be many of it, I have already found 7 pieces.

picture 1, Crocus ligusticus (medius) with virus
Thanks for the names Udo.
Should I destroy the virused C. ligusticus?
Yes, it is better absolutely to destroy the struck plants. Otherwise, aphides or other animals could infect other plants.

I, like Tony W, have had autumn rot, roots too. Not for several years now though. My problems came in years when I watered early and the weather stayed warm. I think warm and wet is the starting point for this problem. Now I delay watering pots until later, when the weather has cooled and the nights are a little longer. Since this change, no rots. In the garden soil you do not have the same issue with heating up. Once cooled by rainfall the great mass of soil does not heat up so easily or so much as a pot.
If you suffer such sever frost as to heave up the soil, I'd be planting Crocus in a sand bed. I have had C tournefortii in a sand bed here for many years ..... but it does fine in light, sandy garden soil too.
-
And finally Crocus tournefortii - or is it a hybrid?
Poul
How do we tell? :)
It looks within the range of what I have grown as C tournefortii. The only x boryi I grow is pure white but much more vigorous than any other boryi that I have grown, even increasing in the open garden like C tournefortii does. It is the vigour that leads me to think it a hybrid ...... BUT seedlings have bred true so far, not any variation which I would expect from offspring of a hybrid. The flowers do not completely close at night. C tournefortii stay open, C boryi close. Half way and maybe it is a hybrid.

THanks Tony
yes we get very severe frost here in Michigan- the ground is frozen for up to 3-4 months, and frost to depths up to of 2 feet or more in unprotected areas, is not uncommon. "Black Frost" - deep freezes with no snow cover is the norm. Our frost line per the building code is 42 inches, that is why i have the frames next to my house foundation to get the warmth of the house.
I don't think the cold bothers too many crocuses (if they dont heave or have roots exposed too long) , it just delays flowering to when it warms up.
I need more sunny sand beds!

Hi Tony I find Your explantion interesting. My experience also indicate very careful watering in the autum. I follow Ian Young's modus with the two storms. This year we have a very warm october in Denmark, which give my some thoughts about extra watering, at least to the specieces with leafs. I killed some bulbs over the past 10 years, not only Crocus but also Tulips, Colchicums and Fritillarias, where I blame my watering as the main reason, and not the Cold weather as many others forumistas.

Yes, watering is critical in so many ways. Always this is in combination with other factors. Very free draining compost/soil (might be pure sand even) will allow excess water to quickly pass through - assuming pots do not stand in a puddle! Extreme cold will be much more likely to cause harm when combined with wet conditions. In a recent winter we had extreme low temperatures in early December. Many of my potted bulbs were still quite wet after late autumn watering (like you I was concerned after a mild spell,) the complete freeze to -10C for over a week killed many bulbs that I had grown in the same site for ten or more years. If I had not watered or if the freeze had come one month later perhaps the damage would have been less.
-
My springflowering Crocuses gives no trouble at all, despite some Cold Winters in Denmark - they is grown in claypots. My loses is primarily amongst the autumnflowering. These years my autumflowering Crocuses is grown in plasticpots,, dug into a sandbed - about 5 - 7 cm. My focus with digging the pots down is to give the bulbs and roots some protection. Until now I'm more happy with this solution, but having trouble with some of the more tender autumspecies, eg. C. hyemalis, cambessedesi.

Rimmer
I agree if it stays constantly frosty. Fatal are situations when a warm weather period caused prematurely growth followed by days with deep black frost. So happend Feb. 2012. I've found almost all shots break off at the base by soil heave up due extreme temperature fluctuations (i.e. sunny day +12°C / clear nights -18°C). My raised beds with a moist sandy soil (w/o top protection) heaved up more compared to a heavy loam soil with sod (my meadow).

is this problem due to too much moisture or inconsistent moisture after being covered and baked all summer?
We have had a lot of rain recently and these are in an open frame.
i have had this problem of stems aborting before with other fall crocus coming into bloom after heavy rain.
I suppose that this is some disease. I had similar in some years in few pots. If it would be overwatering - all corms would show same symptoms, but usually it is only 1-2 specimens in pot with 5 - 16 corms in each.

just a couple of Crocus serotinus

I agree if it stays constantly frosty. Fatal are situations when a warm weather period caused prematurely growth followed by days with deep black frost. So happend Feb. 2012. I've found almost all shots break off at the base by soil heave up due extreme temperature fluctuations (i.e. sunny day +12°C / clear nights -18°C). My raised beds with a moist sandy soil (w/o top protection) heaved up more compared to a heavy loam soil with sod (my meadow).

I have similar winter conditions and agree that it is most dangerous. But I start watering in first days of September and I'm doing it once a week up to frost starts. My substrate is very well drained. Now I started to change it (trying) - 3 parts of coarse sand and 1 part of peat moss + dolomite chalk and complex fertilizer. First two waterings - pure water after that 0,2 % fertilizer solution - NPK - 6-12-18+microelements. Crocus vallicola, autranii, suworovianus, banaticus get first watering in mid-August.

I unpotted the plants and yes 2 bulbs were soft and grayish, the other two were firm and had good root systems- the good bulbs are in the open ground in sand now. All 4 bulbs are from 1 bulb i started with last fall from PC

Crocus tournefortii
From an old Norman Hadden collection; Greece, Mykonos.

I got an autumn flowering crocus from plant exchange in the spring, and was surprised how hardy it is. I noticed the flower coming up little over a week ago, and right after that we had couple of very cold nights, minimum -7,5°C and the days were barely over zero. Now it is warmer again, days +10°C and the little flower had not been damaged at all by the frost. I don't know the species, and there hasn't been enough sun for it to open the flower. I suppose it is impossible to know the species form this picture?

Hi Leena!
The crocus at your photo should be Crocus speciosus.
They are very hardy.
Kind regards. Daniel
-
Thank you Daniel. :)
It is good it is so hardy (and it flowers so late that there are no other flowers left, so that is good). Perhaps some earlier flowering species would still be better to grow here.
-
Thank you Daniel. :)

There are earlier forms of speciosus, too. May be white Crocus vallicola could alive. I think Crocus kotschyanus could be hardy, too.

Crocus cartwrightianus Albus

Thank you for these suggestions, I will try to keep them in mind when the time comes to order new bulbs in the spring, because I would love to have more or these autumn flowering species. :)

Hello all, this is my first flowering crocus of this season.
Crocus mathewii, from Janis in 2012.
-
Hi Tatsuo,
your Crocus mathewii looks good,
here two new Crocus this weekend in flower:
Crocus ( biforus ssp. ) melantherus from southern Greece
'' caspius from northern Iran

I like this form of melantherus Dirk ! Good black anthers .
I have some seedlings from caspius , now I can see how they hopefully wil be in the future ..

Absolutely crazy year. Not only in United Kingdom with horrible storm (we wait it here tonight) but with plants, too. Today here is +15 C so I maid some last job in my "bee farm" - took of anti-varroa medicine. Of course got some "anti-rheumatic injections". But yesterday all crocus flowers were full with bees and they flew as in summer.
Are blooming not only autumn crocuses but even some spring bloomers started to flower. Surprisingly (luckily!) - not spring crocuses but Corydalis schanginii from Kazakhstan and one stock of Ornithogalum lanceolatum. I read on internet that it could bloom in autumn and read about this in best German garden magazine "Gartenpraxis" but by myself saw it for the first time. From crocuses in this entry 2 pictures of Crocus speciosus subsp. hellenicus - described by me this summer in "The Alpine Gardener" and supplement. Here it is one of latest from C. speciosus group, but very pretty - something similar to Turkish subsp. elegans from near Akseki.
-
Absolutely last from speciosus group this year is subsp. sakariensis. Unfortunately not pictured it yesterday when flowers were open to show its bright yellow throat and tall stigmatic branches well overpassing anthers. Today is very cloudy and flowers are tightly closed.
Nicely yesterday bloomed Greek mainland Crocus laevigatus - variously coloured forms.
-
Nicely are blooming Crocus cambessedesii
Surprisingly late is this form of Crocus wattiorum from P&P Watt which I got through Jim Archibald
Very unusual is this Crocus goulimyi named by its discoverer Melvin Jope as 'Agia Sophia'
An as last for today is Crocus melantherus - form with stippled back and only slightly noticeable black connective of anthers. Regardless of its name "melantherus" (black anthered) there are plenty of plants with pure yellow anthers, too.

When repotting crocus corms sown in November 2009 and labelled Crocus biflorus pulchricolor x chrysanthus I thought one was big enough to flower and got all excited. It is flowering now and is pulchellus :'( The packet of seed was a freebie from the SRGC Discussion weekend in 2009.

Crocus pulchellus "Michael Hoog"
all blooms have been distorted like this
is this virused?

Yes, I think so. If only one flower affected maybe some doubt but all three - it looks bad :(

what happens if a virused crocus is left in a collection? does the whole collect run the risk of catching this virus if aphids or other vectors show up?

;D

It looks as virus. But it can be caused by some other reason, too. This year I had similar Michael Hoog, although earlier it looked perfect. And all plants looked same (I have around 100 corms - 8 pots with 12-16 in each). Similar problem is with kotschyanus leucopharynx seedlings - they all formed only similarly looking flowers. They bloomed for first time last autumn and it is only second blooming. And all flowers looks same. I don't think that they get virus so quickly. C. pulchellus Michael Hoog is old variety, so in this virus infection is more possible. But I will wait till next season before deciding to keep or destroy the stock. Sometimes it is caused by replanting and keeping of corms out of soil. Of course I replaced my pots to so named quarantine - where I can observe them and to protect other stocks from possible infection. Sometimes virus is hided under good growing conditions and appear only under unfavourable situation. Similar damage can be caused by bulb scale mite, but then corms will die completely during one season. It is quite great problem in milder climatic conditions and several collections in Germany, Holland, UK seriously suffers from it. Here I think winters are too cold. We discussed problem with Henrik Zetterlund. By him dangerous is combination of mite and fungal disease.

We passed difficult day without electricity after horrible wind during most of night. Wind blowed away bed cover, around wooden sticks separating stocks soil was blown away and even a lot of sticks were "picked" out. The black film (geotextile) sheet 50 x 10 m large (used to cover soil against weeds) was picked up and pushed high in trees - you can see this on first 3 pictures. Damage to greenhouses were minimal - only few windows were broken but generally all was repaired during this day. In greenhouse continue blooming of autumn crocuses. In this entry a pair of rarities - just described by me Crocus macedonicus and quite difficult for growing but very beautiful Crocus moabiticus.
-
what happens if a virused crocus is left in a collection? does the whole collect run the risk of catching this virus if aphids or other vectors show up?
Yes, that can happen!

What a terrible disaster, Janis :o :( Really hoping your plant collections haven’t got severe damages. And I’ve already added those two crocuses on the top of my wish list yet :P
Here is a very popular Crocus pulchellus, JJA350.409 (Ex R. & R. Wallis 01-34.). This is the first flower from seed, sown in Oct. 2009.

If they will grow well - macedonicus may be will be available next year. I collected a lot of seeds from this one and I have full box with seedlings. C. moabiticus I pollinated but as I have only one blooming plant, seed crop could be very small or even absent. Several crocuses are self-sterile.

Crocus pulchellus isn't very variable although it is growing on large territory. Here you can see some variants collected on Athos peninsula in continental Greece where I looked for Crocus vaclavii and others are from various locations on Chios Island just at Turkish border. Variations - intensity of colour, shape of petals, blooming time.
-
One more pulchellus from Chios - the lightest at present
Then some subsp. of speciosus - xantholaimos, sakariensis and hellenicus. Note the branching of stigma and its position in xantholaimos and sakariensis.
as last
Crocus veneris
-
Now 2 pictures of Crocus aleppicus from Israel
Then crocus cancellatus (?) from Jordania
Crocus ochroleucus from Israel kindly sent to me by Oron
and Crocus pallasii Alba - baught from Antoine Hoog
-
Crocus boryi from Lefkada is one of the latest boryi blooming this season. The blooming sequence is not very constant but stock marked as earliest allways blooms at start of "boryi" season
Crocus cartwrightianus from Crete some growers are naming as "subsp. cretensis"
Here white form of Crocus caspius although flower colour can change - first flowers come out white and the last ones (from second wave of blooms) are light lilac
Crocus laevigatus pumila is very variable by colour. Those plants all were collected in same population on Mnt. Vouvala, Crete
Crocus ligusticus is not easy to obtain and to grow. Here healthy specimen from N Italy originally collected by Thomas Huber. More known under old name of C. medius.
-
The last entry for today
Crocus nerimaniae blooming in seedling section - it had only 2 growing seasons from sawing when maid first flower
This is extremely late Crocus mazziaricus from W Turkey.
And last - Crocus longiflorus from Sicily got via Erich Pasche.
-
It took me a few years, but I finally found a seller with good (true?) coloured Crocus mathewii 'Dream Dancer'. This one I acquired last September and it puts my "other" Dream Dancer in the shade.
I am very happy to have it.
It is the first time I put a Crocus in a pot instead of in the garden. I wanted to be sure to get seeds of it, so it is basking in the sun on my window sill and being utterly harrased by my paintbrush the last couple of days, although the stamen and stigmas are quite short on this one.
-
It looks true John. I don't know - is C.mathewii self-fertile or not. In any case better to pollinate it with another mathewii (not Dream Dancer - clone can be selfsterile on all specimens - you need another form, clone).
-
Thank you Janis. I will do what you have advised.

Crocus gilanicus from the balmy days of early October.
(http://farm4.staticflickr.com/3717/11613317685_fcd71629b4_o.jpg)
A crocus with a rather subtle understated charm.

Quite a bonny wee thing when warm sunlight encourages the flower to open wildly.
