Title: Crocus January and February 2019
Post by: Yann on January 01, 2019, 03:28:42 PM
In 2015 i collected seeds of Crocus near Başyayla, Turkey. Several pots are flowering for the first time. The bad and rainy weather has damaged the flowers and yellowed the leafs. I'm thinking of Crocus taurii. Anyone can confirm?

I'm afraid that it is not C.taurii. At first the distance between yours locality (if I found it correctly on Google Earth) and locality of C. taurii according HKEP is around 500 km, C. taurii in general is blue, rarely whitish. Here I'm attaching some of my pictures of crocus which I regard as taurii.

Today I got nice mail from Germany with attached photo of pink Crocus alatavicus (I'm attaching it here). In 2017 I sent abroad 2 corms of it - one was sent to Japan, another to Germany. With me left the smallest from 3 what I had. This picture inspired me to visit greenhouse where some days ago I took of the cover, because in became too warm below it. Today in greenhouse was + 4 C (outside +1-2 C). Checking my pot with my corm of pink alatavicus I found 2 noses just-just at soil surface, so I hope again for 2 corms this season. But most of crocuses still are sleeping. Only one more flower of C. caspius came out, started blooming one acquisition of C. laevigatus and still are blooming C. cartwrightianus cretense, laevigatus, pumilus and few boryi. From so named spring bloomers - only 2 pots with hittiticus - others only showed tips of leaves. Last year at this time they were in full bloom. Leaves of mine newly published C. hatayensis at present are around 20 cm long, whilst kotschyanus just just show noses on few pots. Weather broadcast warns about dropping of temperature up to minus 12 after 2 days, so after tomorrow most likely again will cover plantings. Frost wave will be around one week and then again + temperatures are announced for most of January.

I've a taurii from you, a dark form, almost blooming. I remind hower having grown a really pale form i lost in 2017.
The JJVV-015 has similar segments.

I collected seeds near the lake of Ermenek while searching for a rare Ophrys.

JR-221 - is it cataloguers number? If so - from which year?
Here after two days of strong wing and snowstorm (with little snow, would like more) started moderate frost. Tonight (and for coming 3-4 nights) minus 8 C, but after week for two nights dropping down to minus 20 C is proposed. Hope this will not come, but winter must to start. Today I will return covering with night frost protection film, but if really will be serious cooling , glass wool sheets will be returned.

A couple of crocus in flower here.  Hoping for colder weather for another six weeks or so ... some hope  :-\

Crocus chrysanthus S0225 - the sole survivor from several collections David S shared sixteen years ago.  From Greece, between Drama and Xanthi.  I have seed raised progeny from a couple of the others.

Crocus hartmannianus from Crocus Group seed sown 2015.   It's nice to think that careful cultivation and sharing of seeds/plants allows us to grow these very rare plants and perhaps in time contribute to their future survival in the wild.

I can only envy you all. We had snowing and snowing - already twice our entry road was cleaned from excessive snow and temperature is slowly dropping, tonight we had minus 7 C, for next even minus 13 offered, then something less but around minus 5-7 C. Of course nothing blooms. In greenhouse when it is sun - temperature rises up to + 10 C, but everything is covered and below cover at top of pots is +0.5-1.0 C, at pot bottom + 1.5-2 C. Some days ago I returned glass-wool sheets to protect against harder frosts. Hope that in March will be possible to open covering, because I announced OPEN DOOR days 16-17 th of March. Usually most of crocuses then are in flowers. Last year we had around 800 visitors and everyone will be welcome.
Servers of my home-page were attached and for 3 days it was impossible to open it, but this morning everything is repaired and again works.

Janis life seems difficult with those temperatures. Here we have only had -2c on three nights so far. It is too warm for the crocuses and other bulbs. If the sun comes out it gets to 20c in the greenhouse so difficult in a different way.

Title: Re: Crocus January and February 2019
Post by: Steve Garvie on January 21, 2019, 10:57:29 PM
Thank you for your kind words Kris.
You only see images of my successes and not the many failures.  ;)

Previously I grew Crocus in shallow clay pots in 40% grit/30% loam/30% composted bark. I lost a lot of plants in the past due to rot. The climate here is cool, damp and I am heavy-handed with watering. As a result I have had a lot of problems with Botrytis -usually starting in the spent flowers. Most of my winter-growing bulbous plants are in a partitioned well-ventilated 20ft x 8ft (6.1x2.5m) greenhouse where they grow in plunged clay pots. The plunge beds have thermostatically-controlled heating cables which activate below 4°C. The greenhouse also has a number of small fans which switch on and off many times -both day and night.

Despite all of the above the high humidity in the air and low winter light levels remained a real problem -especially when the weather was mild. So more recently I decided to turn it all on its head.
I now use long tom pots with a very sharply-drained inorganic potting mix for all of my crocus (and frits and iris......). I lined the greenhouse with insulating bubble plastic, closed the vents and have installed a dehumidifier set to keep the air humidity below 65%. I have also installed various led lights. It is early days yet but the drier air seems to be making a real difference as is the extra light during the short winter days.   

The downside is a significant increase in our electricity bills and a garden that looks like a parking lot for alien spacecraft!

Crocus hartmannianus in flower here. I have two different clones, the one purchased from Janis having broader petals. When back-lit the markings on the reverse of the tepals show through.

Do you recycle the water from the dehumidifier? Few off us can do that ;-) I have used only rain water for many years and although I cover all my collection tanks I wonder if I might have healthier plants using chlorinated water. If only I was not in a chalky area.

Can you clarify "inorganic" potting mix for me please? As a chemist I find the use of carbon compound free growing mediums interesting. Growing house plant bulbs in glass beads was popular many years ago I recall.
Title: Re: Crocus January and February 2019
Post by: Steve Garvie on January 22, 2019, 06:25:35 PM
Thanks for your questions Brian.
Yes I have been recycling the water as it is useful for watering certain types of orchid (North American bog orchids, certain pleiones, etc). However the dehumidifier needs emptied almost daily as it is pulling over 3 litres per day from the greenhouse atmosphere and so I am tempted to use a continuous drainage pipe.

As regards my “inorganic” potting mix I mean that there is no humus content in my mixes (so no loam, peat, composted bark or leafmould). I use a mixture of perlite, 3-8mm grade pumice, coarse sand, granite grit, zeolite and often limestone chippings with powdered dolomitic lime. If I was being pedantic I would have to admit that the mixes are not totally carbon-free as I do add some powdered bonemeal to the mix whilst there are clearly carbonates in the limestone. I sometimes also add a little fine grade biochar depending upon the bulbs I’m growing.

I’m no soil scientist and appreciate that this is an over-simplification but amongst other things organic compounds in the soil bind macronutrients and encourage the development of beneficial microbial populations which can free-up micro-nutrients. Organic material also holds water in the soil.
However, in a pot containing a summer-dormant bulb (corm/tuber/rhizome) the retention of water is undesireable whilst organic material is more likely to encourage saprophytic fungi/oomycetes (many of which are facultative plant pathogens) than beneficial bugs. Adding small amounts of biochar and Clinoptilolite (a type of zeolite) to inorganic soil mixes will, by adsorption and cation exchange respectively, hold any added fertilisers and prevent nutrient leaching. I am now using chempak micronutrients fertiliser with my first autumnal watering and once again in the Spring, otherwise I feed with dilute tomato feed most waterings. This is all an evolving process and I will make further changes depending on results. However I am now no longer killing Onco and Juno iris whilst difficult semi-desert crocus such as moabiticus seem to be doing quite well.

As an aside, it might be worth adding a small amount of hydrogen peroxide to your water butts periodically to keep the water “sweet”. Five litre containers of 3% peroxide (food grade) are available from many catering suppliers for under £8.

Oh happy people. Here started real winter. A night before temperature dropped down to minus 24 C at my locality. Wonderful view outside - see attached pictures - flowers designed by frost and sun only.
Inside greenhouse - you can see my bulb house for potted plants on 2nd picture - temperature during night dropped to minus 13 C only. The "warm" was kept in due snow cover on roof. All beds are covered now with glass-wool and below cover at top of pots (below crocus leaves) temperature still is around +1 C, but at bottom of pots +2 C, so I'm still not worried. All the day temperature stayed at around minus 14 C, but in late evening and during last night was some "warming" and temperature didn't fell below minus 7 C. You can see covered crocus beds in my earlier entries, so I not repeat them here.
The 3rd picture shows outside fields. Snow level is good - more than 20 cm and only tops of sticks separating stocks and hare footprints are visible.

Post by: colin e on January 23, 2019, 09:29:41 AM
Steve I do not know if this is relevant to your dehumidifier, but something you may want to bear in mind is that some have a copper element for the water vapour to condense on (or used to). If this is the case, the very soft water can take on some of the copper though this is probably not enough (?) to affect plants depending on how sensitive they are. The reason I say this is that I have killed fish because of this (I did not know about the copper element when this happened) and it took some time to figure out were the copper came from!  Just thought you might like to know.

Colin
Title: Re: Crocus January and February 2019
Post by: Steve Garvie on January 23, 2019, 09:58:51 AM
Many thanks for this advice Colin. As you say copper is very toxic to aquatic life but paradoxically is also an effective treatment for Oomycetes (water-bourne moulds) such as Phytophthora, Pythium and Fusarium which all cause serious root rots. I still remember old aquarists using copper pennies to treat Ich.   ;)

Conventional condensing dehumidifiers are of almost no use in a cool greenhouse as the coils freeze up and the dehumidifier becomes very inefficient. I use a dessicant dehumidifier which draws the cool damp air over a rotating zeolite disk. Water is absorbed by the zeolite which is then heated to discharge the water and replenish the zeolite -the water that is collected is very pure with little cation leakage from the zeolite (though it is probably best to discard this water for the first few weeks of operation). The air that is discharged from the dehumidifier is warmer. These types of dehumidifier are especially cost-effective in greenhouses where there is some additional gentle heating as they raise air temperature by a few degrees whilst it also requires less energy to heat dry air to a given temperature than it does moist air.

Regardless of minus 13 C outside I'm not out of crocuses. I'm shortening time which will be needed in summer. I'm always at collecting and harvesting collecting corm tunics, too. Now is time to open small packets, to check them and to make pictures + description on matrix, used for each sample. Now I'm working on last seasons Iranian gatherings. Between corm shells in one packet I found excellent seed pod, collected in Iran, so it was possible to add picture of seed pod and seeds and to describe them in my notes. Will it be new species or will be identified as Crocus iranicus, without leaves and flowers I can't judge now. This stock was observed on steep slope growing in dense grass near very large Anemone field of various colours. Seeds were cleaned and sawn. Fortunately I had several pots with soil prepared for some unexpected or late coming seeds. Pots were frozen but I brought them in cool veranda, where they defrosted, saw the seeds and several times put on top large snowball - to water seeds with snow-melt water, as it happens in nature. Some are telling that this stimulates germination. I don't know, but it is easy way when you have outside 35 cm of snow. View to one part of garden this morning on the last picture.

Crocus pelistericus white form
Excellent plant, but IT IS NOT PELISTERICUS. Check the leaves! On the picture the leaf has white median stripe! But C. pelistericus leave are without the white median stripe! Or it is optical illusion ?

Yesterday we had +2 C and rain changing to heavy snowstorm in afternoon. I used wet snow to make snowman on top of recently sawn crocus pot to use melting water for watering of seeds and substrate. But in night frost returned, again outside are minuses, but nothing dramatical is offered for February. Only sparrows are sitting with backs together on their feeding table - to save the warm. I wait spring! All winter paperworks are done, I tired from waiting...

Janis thank you for your observations but you are incorrect and it is Crocus pelistericus. What you have seen as the white stripe is in fact part of the silver bract showing between two leaves. I have in previous years crossed it with C. scardicus and produced seed which would not have been possible as my understanding is crocuses do not produce intersectional hybrids.

Tony, I commented only what I saw on the picture, where it is impossible to recognize 2 leaves with bract between. Sorry!

All beautiful .... and thank you for helping me update my knowledge.  I thought that Crocus yalovensis looked like what I until recently called Crocus pestalozzae var caeruleus and then changed to Crocus violaceus.  After a little research I found the article in IRG that tells of the latest name change for my old friend!  At least I now know my eyes did not deceive me  ;D

Yes lots of changes among iridaceae, and its only the start of a new world for botanic.
DNA is now widely used in phylogeny, all what we learnt between the 70's and 90's is now obsolete.

Recently i was talking with a friend about Lysimachia arvensis, he didn't even know of the change 20 years ago :)
Even the book still mention Anagallis.

Botanic is a living science, what we thought right yesterday is wrong tomorrow  ;D

Irises now are proposed to split into 23 genus... See Phytotaxa, 232 (1): 001-078 - MANUEL B. CRESPO, MARIO MARTÍNEZ-AZORÍN & EVGENY V. MAVRODIEV
Can a rainbow consist of a single colour? A new comprehensive generic arrangement of the ‘Iris sensu latissimo’ clade (Iridaceae), congruent with morphology and molecular data.

Nothing special, but beautiful nonetheless.. Crocus korolkowii (of the Agalik persuasion).

I'd vote for  heuffellianus too, or  perhaps  vernus  heuffellianus if I  had no shortage of ink!
On the Plant List,  Crocus vernus var. leucorhynchus Sabine is given as a synonym of Crocus vernus (L.) Hill -but  it doesn't appear in IPNI.
 Names, eh?!!

I just returned from Portugal. I was invited to join small group of daffodil lovers and I really enjoyed them growing on rocks. We found some very exclusive things, too. My target was re checking of Crocus duncanii, especially after Kerndorff's article in Stapfia putting under doubt this very special crocus. Now the pine forest at its locus classicus was cut off, but Crocus duncanii was in full bloom very well showing its main specific features - very narrow, elongated flower segments, deep position of corm in soil with long tunics neck. The position of stigma was not so constant, now only 2 observed plants had stigma overtopping anthers. When I discovered this crocus it was just opposite. But my observations showed that this is very variable feature and more depends from age of flower.
But the most interesting was pH level. Of course - C. duncanii as plant from pine forest had very acid soil pH around 5, but the same was the soil where in completely different conditions were growing Crocus salzmannii and Crocus clusii. The universal indicator solution used on small pinch of soil coloured red - indicating very acid soil.

Two days ago I returned from Portugal trip. Unfortunately I got some flu and only yesterday for few minutes visited greenhouse for some pictures. In this entry some Crocus korolkowii seedlings of unusual colour. Possibly they are hybrids. All were marked last spring.

Some more Central Asian crocuses. The first is pink form of C. alatavicus. Then very old cultivar of C. korolkowii 'Dytiscus' selected from wild material by E.A. Bowles. Following 3 show two hybrids (?) selected by Augis Dambrauskas, but I suppose that they are mutations of C. korolkowii - Lemon Alatau (Augis suppose that bee brought pollen of C. alatavicus) and 2 pictures of 'Snow Tiger' (supposed hybrid with michelsonii).

Started mass blooming of crocuses in greenhouse but outside in protected spot the earliest came out C. korolkowii. Great surprise for me was flower buds of C. atticus in outside garden. But this afternoon I used some hours of sun for pictures and garden notes. In total 420 shots were done and today the first 5 here. Pity, that I remain the last crocus forumist as most likely in rest of Europe Crocus blooming already finished or is close to it.
The first is Crocus sieberi hybrid Hubert Edelsten. Its mutant George only shows tips of buds out of soil, but blooms something similar to it wild form from Omalos, Crete.
Next is Crocus muglaensis
After that one aquisition of Crocus caricus - one of the most beautiful wild species
and as last - Crocus kurdistanicus from Iran got from Jim Archibald.
