Title: Crocus autumn - 2020
Post by: Janis Ruksans on July 11, 2020, 05:59:20 AM
Just harvested Crocus pelistericus. Leaves still were green, but you can see how well developed are new roots. It is most problematic to find best repotting time for this species. Last week I harvested corms which were ordered by my customers and new roots still were much less developed. The main secret for growing this crocus is correct substrate - it must be acid. I checked it in wild. It don't need keeping in trays with water etc. only I'm bringing its pots out of greenhouse when weather permits (just after blooming).
 Now I'm buying rhododendron and conifer mix, adding 2-3 parts by volume of coarse sand and use it for pelistericus, veluchensis, duncanii, carpetanus and yalovensis. The difference of medium pH on Crocus veluchensis you can see on 2nd picture - there were planted 2 pots with same number and size of C. cf. veluchensis - on left acid medium (pH around 5 or even below, on right standard mix (pH 6.5-7).

Thank you for sharing these insights with us Janis. Amazing effect.
Are you also using this kind of substrate for C. sharojanii flavus?

It is most problematic to find best repotting time for this species.

I couldn't agree more! I've been growing C.pelistericus for nearly twenty years now and it's a perennial puzzle knowing when to repot. In some years it is almost evergreen and I have completed the task towards the end of September, (in the English Midlands); more recently I tend to do this in the second  or third week of September, as in the photo attached, taken back in 2018. As you can see, the problem then is that root growth is starting and next year's flower buds are already well developed. It must be a nightmare to grow commercially if your customers are expecting 'normal' corms in autumn!

Interesting to hear your view about its pH requirements. I had previously mixed a healthy proportion of peat with JI No 2, coarse sand and grit, but in the last few years I have also included Melcourt propagating bark; I expect that the peat and bark help to bring the pH down quite a lot, but I've never measured this. I have used similar composts successfully for such as C. thirkeanus and from what you say it could benefit quite a few species.

I also agree heartily with your advice not to stand it in trays of water. I expect that photos of the plant in the wild more or less submerged in running snow-melt have contributed to this idea. It certainly likes plenty of water, but not stagnant water. I grow mine outside, in pots, open to the elements all year except when in flower, or when severe frosts are forecast. And I won't make you laugh Janis by saying what I consider to be a severe frost!

After almost 3 weeks long interruption (hospital etc.) I returned to repotting of crocuses. Found that C. autranii already showed new shoots. Still surprised for crop - got incredibly large corms of Turkish Crocus fleischeri (from Chios Island - of usual size). C. pulchricolor formed minor corms but C. zetterlundii (earlier included in pulchricolor) formed so large as never before. The same I can tell about demirisianus and fauseri.

Yesterday got shocking mail from customer in UK (his initials are GS): "Also you have not sent all bulbs that i have paid for.missing is number9-151-202-206-216-220-275-403-404.I shall not be doing any more business with you Janis if this is what you do." - but he never ordered those plants. Checked all his mails - found 2 orders (very chaotic) but in no one were those numbers. Actually it is the first such letter from customer during 30 years of my export business...

A very good start of the Crocus season!

I have been strugling to get flowers in my Crocus scharojanii. They are much more difficult than C. scharojanii flavus, which flower reliably every year for me.
In 2015 I tried crossing these two in hope of getting a more reliable flowering of a deep yellow autumn Crocus. The crossing was succesfull and I got some seedpods on C. scharojanii flavus.
The seeds were sowed in 2016 and I got 12 seedlings. 4 of them died the first year, but 8 were growing well. This spring one had 4 leaves, one had 3 leaves and the rest only 2 leaves.
The leaves withered a few weeks ago and I hoped for the 4-leaved corm to flower for the first time this season. However I was very surprised that 7 out of 8 corms send up flower shoots! :o
That is exceptional good for first time flowering. It seems that my dream of a reliable deep yellow Crocus has come true ;D ;D ;D

Title: Re: Crocus autumn - 2020
Post by: pehe on August 10, 2020, 06:06:01 AM
In Denmark we “only” have 32 oC at the moment, so it is not autumn here, but we had had one of the coolest July.
I grow them in a bed facing North West. The bed is shaded most of the day by some Rhododrendron. Late in the afternoon they get about 2 hours sun, but now when it is so hot, I have put up a white shade so they do not get any sun. I keep the sand where they are plunged moist all the time.
One of the parents C. Scharojanii flavus grows well in another bed with about 5 hours sun a day, but also kept moist all the time.

Most years (and also this year) Janis has C. scharojanii flavus in his catalogue: https://rarebulbs.lv/index.php/en/catal (https://rarebulbs.lv/index.php/en/catal)
The pure C. scharojanii is harder to get hold of and right now I am not aware of any source.

Does it mean:
Crocus scharojanii var. flavus (like in the book of J. Ruksans)
or
Crocus scharojanii X flavus (like p.e. on the page of Michael Camphausen)

C. flavus flowers at March(April, so i think it would be var. flavus?

Crocus scharojanii var. flavus is a Natural hybrid between scharojanii and vallicola.
My plants are a hybrid between scharojanii var. flavus and scharojanii.
I do not think that Crocus flavus could hybridize with Crocus scharojanii.

Poul
Title: Re: Crocus autumn - 2020
Post by: Tristan_He on August 23, 2020, 10:35:33 AM
Since it is a hybrid and not a variety, C. scharojanii var. flavus presumably needs a new name anyway. One for the taxonomists....
Title: Re: Crocus autumn - 2020

agree  :)

P.e. Paphiopedilum has an natural hybrid Paphiopedilum X AngThong = P. niveum x P. godefroyae

For this Cocus, i think: Crocus X Flavus ???

I think that would be a bad name. It is too close to the species Crocus flavus and I am sure it will make a lot of confusion.

I'm not professional taxonomist, but I think that name scharojanii var. flavus can be used, at least so it was published. Varietal level don't conflict with species name, so it is legal. WCSP list it as hybrid between vallicola and suworovianus, what certainly isn't true. I didn't saw original publication of this epithet, so I don't know how validly it is published.
Title: Re: Crocus autumn - 2020
Post by: Janis Ruksans on August 24, 2020, 06:37:41 PM
Yesterday I finished re-potting of crocuses. Last species were laevigatus, melantherus and boryi. Usually I was disappointed with boryi, but this year they produced excellent corms, larger than usually in this species. C. laevigatus - in opposite - made smaller corms than usually. This year it was easy to separate boryi from laevigatus by shape of corms - in boryi they were very round, but in laevigatus distinctly elongated. As usually in last years greatest losses were between species from pallasii group, but those which alive were of huge size. I already wrote that small replacement corms were formed by Central Asian species, although leaves were very large. Different species had different reaction on abnormal spring conditions. I suppose that starting of growing in the darkest days of year in December/January gave too little light for good corm crop to earliest species.
Serious enemy turned black ants. On pictures you can see same sample of Crocus cf. mazziaricus - on the first picture are corms harvested from pot which was invaded by ants, on the next the same acquisition number from pot without ants. Note 5 cm long shoots at repotting time on some corms.

Poul, amazing pictures of your C. scharojanii crossings and thanks for sharing them.
I myself have (of course) been looking for a long time for the pure C. scharojanii but yet without any luck. I am even starting to wonder if there are any other plantsmen out there who have it all in there collection? (except for Janis I don't know of any other people).
I am even considering to go and visit it in it's original native habitat one day in order to get hold off some seed, would anybody know when would be the best bet to harvest the ripe seedpods for this species? My aim would be to re-introduce this species in as much private collections as possible in order to safeguard it from potential extinction due to habitat loss.

Unfortunately I have only 1 poor corm of scharojanii. Covid broke all plans to visit Caucasus and collect some new stock and to check soil pH at their natural habitat.
As I wrote before, I was almost 3 weeks out of working capacity this summer. Waiting in lines in hospital for treatments, I had with old favourite, written more than 100 years ago - E. A. Bowles trilogy "My garden in ...".  "...in Spring" on page 89 he wrote that Crocus aerius below ground has "thin jacket instead of the hard shell-like covering of chrysanthus". And yes, most of chrysanthus sensu lato has hard corm tunics. One was separated by me many years ago by its very thin, papery tunics growing far to East in Turkey, and this summer I published it as new species naming after Doerte Harpke from Gaterslebren Institute of Plant Genetics as Crocus harpkeae.
At harvesting I'm always making notes about corm tunics, collect them in small envelopes for later more diligent exploring. Having quite many samples of so named chrysanthus from Greece, I was surprised by some variability between populations by features regarded by HKEP as important in taxonomy of annulate crocuses.
And here some observations about Greek "chrysanthus":
Sample from N of Drama - tunics thin, basal rings with pronged edge
from Keoax - tunic looks hard, basal rings distinctly toothed, but this is new acquisition and needs more checking.
Mount Kissavos and near Afyon - tunic hard, rings with very long tooth
Near Stavropoli - tunics thin, papyraceous, rings shortly pronged
Are they all the same species, only extremely variable, or similarly to so named "veluchensis" and some others represents several different taxa, can be solved only checking DNA what is not available for me at present.

Thank You, Maggi, You´re right - I think they came up from seed. Growing crocus in my garden is quite an adventure due to the heavy soil and legions of rodents, so every survivor is welcome! Crocus tommasinianus established himself successfully and produced some nice offspring, but other species struggle hard or succombed.

Crocus sativus
I like your sativus - it is practically identical with mine from Greece (see 1st picture). Where from comes yours?
But I have two stocks. Another one comes from Iran (2nd picture) - I dislike it's colour pattern although it is growing very well, but I replaced it out of crocus bed, as I'm afraid that could be present virus infection. Similar I pictured in Gothenburg BG (3rd picture) and found on saffron site in internet (4th picture). In the new book (Medicinal Plants of Afghanistan) received few days ago are 2 pictures of C. sativus with same suspicious pattern of flower colour (5th picture). Is this virus? Or may be only clonal difference? As it is grown by hectares, seem that Iranian-Afgan stocks didn't suffer. I didn't see clones grown in Spain and India etc. Of course appearing of different clones is very possible during so long time of cultivation.

It has stayed in the same spot under a Korean quince ( Cydonia sinensis) with about 4-6 hours of sunlight.

On sunny days greenhouse is full of sweetest scent, but outside... No photogenic picture. Crocuses bloom, but yesterday's snow, rain, hail and hard wind damaged all flowers. It was real hell outside. Fortunately I worked inside greenhouse potting Alliums. Hope to finish this week and then will remain only Tulips. Very late for me this year.

Yesterday finished with filling of pots my new raised bed - there are Alliums and part of Tulip species. Still left ~10 days to plant tulips - other species and own hybrids. After several days of "ignorance" visited my crocuses and really was shocked by incredible beauty of white forms of Crocus cartwrightianus as well as intensively yellowish shaded C. pumilus from Crete - it is darker than usually, but many "white" species had yellowish shade in early flowers this season.
Crocus cartwrightianus albus - commercial form

Passed crocus season really was strange. Started far too early, some species formed small new corms regardless of good foliage, some made excellent corms regardless of weak foliage. As usually there were great losses between pallasii related species, more than usually between hadriaticus forms, but cancellatus group was better than usually is. Without regular renewing of stocks from seeds I could loss most of pallasii group species. Blooming is strange, too. Usually first flowers of C. caspius are white and second ones lilac – this year it was vice-verse. But in general losses were not greater than usually. Far better than year before were species with annulate tunics.

Of course I’m more lucky than my friends in France which had very great problems with keeping of crocuses due very exceptional hot waves. I brought out of greenhouse a lot of pots this year and results were far better than before with species from veluchensis sensu lato group, cvijicii, banaticus and other species from high mountain altitudes.

Still continue blooming and now the most important is taking off died flowers. Yesterday I did this for a pair of hours. Weather broadcast again changed and dark cloudy, wet days offered without sun, so it becomes even more important to prevent mold on died flowers which easy can penetrate down to corm and to kill it.

Beautiful Janis, in particular I really like the Blushing Marmot“.. Fortunately, your Artvin strain bears some blushing ones, too. This year I managed to take a photo of one doing so (colouration was even stronger on the outside), although not as dramatically as the marmot. I’m very grateful for having received this lovely plant. Just a shame my vallicolas did flower one after the other this year, so I could not cross-pollinate. Hope for some seeds through selfing though.

Post by: Janis Ruksans on November 07, 2020, 12:25:24 PM
Most important now is removing of old flowers. On the first picture one such not seen in time flower with penicillium mould - if it will be left, infection could reach and kill corm.
Crocus hatayensis is the last bloomer in C. kotschyanus group - here you can see form received from Erich Pasche and from type gathering pictured in cloudy day, so you can see well developed new leaves.
From speciosus group the latest are C. sakariensis (just finished) and C. cf. hellenicus from Varnakovo (on pictures) - by flower it resembles Turkish brachyphilus, blooming much earlier and is easy separable by striped cataphylls (last picture). Similar cataphylls has C. zubovii from Iran (SE coast of Caspian Sea)

Some crocuses from Israel and Jordania, which bloomed last week - in general earlier than usually.
Crocus hyemalis ILOP-015 from Israel
Much earlier than usually bloomed Crocus moabiticus from near Madaba, Jordania. Its flowers widely opened in sun allowing good hand-pollination.
Crocus ochroleucus from Israel - Massada, Golan Heights, alt. 1050 m is a little similar to kotschyanus, but corms are much smaller and cormlets almost only poppy-seed size.
Corms of Crocus ochroleucus cultivar 'Dalton White' selected by Oron Peri this year was so tiny (largest around 3 mm in diameter) that I didn't hope to see any flower, but one of them bloomed.
Crocus veneris this year blooms unusually early. It is species endemic to the Mediterranean island of Cyprus where it igrow in stony or grassy places in scrub. It flowers there in Autumn and early Winter and is little difficult in cultivation where it usually makes its cheery, star-shaped flowers only from December onwards with me - this season its blooming already approximates end.

Yesterdays sun allowed to make some more pictures of last crocuses, but main job is deleting of old flowers from Crocus and Cyclamen pots. This morning we had first night frost in this autumn - so ahead last watering of pots and wintering of watering systems up to spring. Bulbs rooted excellently - even those Allium and Tulipa potted only 2 weeks ago show white root tips through pots bottom holes.

Again some "spring" crocuses try to run out. May be Crocus hittiticus blooming now must be reclassified as autumn-spring blooming? Last years it always started in December and continued up to spring. Yesterday all the day was snowing. We had strong storm a week ago and one huge spruce (around 90 years old) was broken over Guna's hosta beds, so we got marvelous Christmas tree even with cones to be placed in front yard of our house. On Sunday I put lights on it and yesterday it was additionally decorated with snow. But my main joy - this morning finished 3 weeks old job on my new offer for 2021. Several new rare crocuses are included. You can see it on http://www.rarebulbs.lv/index.php/en/

More and more crocuses are coming out. Today I fixed C. stridii, C. demirizianus, 2 forms of C. fleischeri, C. punctatus. And 2 reticulata irises are blooming, one more muscari (new species from high altitudes in NE Turkay over Altiparmak - offered in new catalogue, too).
As there are no sun last days, flowers didn't open but stay in tight buds.

I don't like bringing of crocus pots from greenhouse into room. My first attempts with replacing of pots on bathrooms windowsill ended with great losses in crop and a pair of very rare plants were lost forever. But there are situations as last season and again this winter when weather is so mild, that some crocuses hurry to come out and stay in closed buds due lack of light and regardless of minor + C degrees, it is quite cool even under cover. And I keep all doors open to press down inner temperature. Some of those are rarities and I need their seeds - so nothing left than bring them for only a pair of hours in warm kitchen to open tightly closed buds, pollinate and immediately back into greenhouse. Even this by my last years experience shows that crocuses don't like such "forcing", actually this could be compared with raping.
In this entry I'm showing very special crocus which I got from Ibrahim as seeds. He gave me some seeds supposing that it s new, autumn blooming species as ripe seeds were collected wild in February. But it turned identical with Crocus demirizianus published by Osman Erol, and collected by me, too at its locus classicus. Regardless of identity by morphology, Ibrahim's plants always blooms earlier than those from type locality - this season it happens just now.

Here still no real winter started. Weather is cool, dark and wet, but some spring blooming bulbs hurry to come out. Two days ago I visited my greenhouse - I got parcel with some crocus corms to be potted immediately (in surprisingly perfect shape, regardless of very long traveling before reach me). I brought in few Crocus pots to force opening. Crocus fleischeri already were in closed buds for some weeks. I brought in pot labeled as C. fleischeri form with brown stigma, having blue striped outside of petals. Really stigma this season at opening had only some brownish shade, but later, when flowers fully opened, it turned dark red. Is it seasonal fluctuation or wrong label? I will see answer next season.
From distance I was shocked seeing yellow buds on one bed where pots with reticulata irises were placed. The first idea - wrong label? It could be impossible to place pot with Iris winogradowii between summer-dry loving species. But when I saw label "Iris bakeriana alba" I was even more surprised. In spring 2017 I together with my Czech friend we spotted on field with Iris bakeriana in Iran one clump with white flowers. White colour in wild reticulatas is extremely rare occasion - I really know only 3 cases - Alan McMurtries 'White Caucasus' , which is slightly bluish, purest white found by Zhirair Basmajyan in Armenia (both are Iris reticulata), and the third is our I. bakeriana. We split this clump between us, but at planting time they looked so poor, that I had no hope for some living bulb. In spring 2018 four very tiny shoots came out with me, but nothing in my friends garden. This autumn I planted four still very small bulbs without any hope to see flowers - but now three flower buds comes out! Still only in bud - I'm afraid to bring them inside, but may be in the New Year, as some frost coming for one week is broadcasted. Although not crocus, it is such rarity, that I can’t withstand attemption to show it here, too.

Yesterday again checked crocus pots and 4 more samples shows tips of flower buds, surprised that usual runners - Central Asian species - alatavicus, michelsonii still are sleeping, but tips of shoots shows only C. korolkowii Alba. From those which I brought in for pictures and pollination - here Crocus stridii from Chalkidiki in Greece, stippled form.
