I think we heard  (from Henrik Zetterlund, Janis? ?) that the hybrid had been found by Arne Seisums.

Ian has remade the cross at home, too.

Hmmm, Oakwood refers to C. x albertii in the post listed above, but  the Kew list says only that :
Colchicum alberti Regel is a synonym of Colchicum kesselringii Regel

This name is a synonym of Colchicum kesselringii Regel.

The record derives from WCSP which reports it as a synonym (record 302753) with original publication details: Trudy Imp. S.-Peterburgsk. Bot. Sada 8: 647 1884.

Thanks Maggi... Not sure that "Oakwoods" plants look anything like Kris' hybrids though, from the pics available, ...do they? Hard to see much C.luteum in "Oakwoods". Given that they have a name (C. x albertii) I am somewhat convinced they do occur naturally, but look like C.kesselringii. Those of Kris do look like those available in 'commerce' so to speak. I guess selected hybrids would run the gamut between both parents.
Has anyone pictured them in the wild?
I've searched for Ians remade cross too, but can't find the pics. Only goes to prove that they will  X however and not that they do so 'au natureal'!
Does the plant 'bulk up' well for you Kris?
Title: Re: Colchicum 2013
Post by: Maggi Young on February 14, 2013, 08:05:18 PM
 I suspect that Oakwood's plants labelled  x alberti  look more like "pure " kesselringii  for which alberti is a synonym.

I will just find some  Bulb Log's with Ian's plants, home made and otherwise.......

luteum x kesselringii 8/04  http://www.srgc.org.uk/bulblog/log2004/190204/log.html (http://www.srgc.org.uk/bulblog/log2004/190204/log.html)
and logs...... 4/05    4/06   7/06     8/07

Edit : As I said, I believe the "wild" cross" was found by Arne Seisums - Janis will be able to confirm this, I think.  I'll have a look in Janis' book to see if I can find a note there.

Thanks Maggi.  Seems it is a natural occurrence?? ???

C. kesselringii doubles each year for me. Does C.luteum do the same?? And the hybrid?? If so, they are surely good 'raised bed plants'?

Lost al my kesselringii's , luteums and also this hybrid previous winter Ron  :( :( :(
But could not resist to buy some new ones in the summer....(not al the different kind of forms , some I could not obtain ....)
So I did not get the chance to know because the hybrid I lost was only for two years in my collection....
But I think it is not a plant that  'bulk up ' well ....Hopefully I get the chance to try now. Anyhow I put them in my frostfree glashouse now  and only put them in the outside bulbframe again after having anough spare bulbs ..... ;D
Title: Re: Colchicum 2013
Post by: Janis Ruksans on February 15, 2013, 07:37:23 AM
There are 3 clones of C. x albertii in cultivation. All were found by Dr. Arnis Seisums in wild, Tadjikistan, near Tovilj-Dara. One of them was named by him 'Janis' and presented to me at my 50th anniversary. Still under question - could it be regarded as true species or as natural hybrid. I haven't at this moment Karin Persson's publication Synopsis of Genus Colchicum at hand, so I can't to check her opinion, and not remember just what she wrote about this. In any case hybrid is fertile and very well set seeds, but my seedlings still didn't started blooming, so I don't know splitting in progeny which could give some conclusion. May be it is stable hybrid on natural way to species?

Given the lack of frost hardiness of Colchicum luteum and relatives I can confirm Maggi and Kris. Last February, the temperature dropped in my alpinehouse a few days at -10 °.  The beautiful Colchicum luteum 'Golden Baby' and Colchicum kesselringii(?) 'Snow of Highland' have not survived. Colchicum luteum x kesselringii 'Jeanne' survived with damage. Perfectly hard was Colchicum kesselringii 'Purple Star'.

Colchicum luteum and keselringii is hardy, as well as hybrid. They are growing wild at 2000 m and higher. Here I grew them outside and minus 10 C for few days is nothing. Afraid that there is another reason - they can easy get Fusarium or other fungal problem. Quite often you can't see infection at planting time.  Purple Star is of same hardiness.
Corms of luteum I collected at Chimgan from totally frosen soil (included in frosted soil), temperatures in night outside was below minus 10. They bloomed without problems from totally frosen soil. Of course hardiness depends from development of plant, too. If very long frost (and strong) returns at blooming time - then plants can die, but then the same will be with many other bulbs (as crocuses), too.

Thanks Janis for your information . You are right ...the main reason for the problems from previous year was the fact that they are near flowering stage when the strong frost came ....They where much  to early in flower (some before the end of the year)because of the very very mild winter . The plants didn't make any preparation against cold. Then suddenly came a strong frost with no snow . And the other problem was the fact that I grewed this bulbs in clay pots....Those clay pots where plunged in a sand bed that was raised above soil level. Due this raised aspect and the sand and clay pots the frost came easily in the pots . The pots where frozen for many weeks . The flowers became black and afterwards they started to rotten ... Some bulbs died because of this fungal disease...I think that other died because the frost was to long in this smal clay pots. In such circumstances the pots are a disadvantage and it was better to have them just in the soil of the garden ? I think I am gonna rebuild this raised bed and would be thinking about some preparations to make it better against such hard frost....And always take a spare bulb in my frostfree glashouse ....But tough ...in the future I wonna try some of those Colchi's in the open garden to ...They are so beautiful that you never wan't to give up ...

I agree with you, Kris.

Thank you from me for your information too, Janis. Last year here in December and January was unusually warm, followed by a sharp frost in February. The plant started as ready to bloom. I think that this was the reason, probably due to a fungal infection. The same thing happened incidentally with Fritillaria sewerzowii.

Mark, what a fine weed -  your Colchicum minutum.

We had several such winters. Some 5-6 years ago I lost most of outgrown bulbs. Last winter losses were minimal regardless of full month with temperature around and below minus 30 C in February. Then damaged were just pots grown on raised beds in polytunnels. 5 cm of foam polyuretane sheets on raised bed sides turned something too little to protect against so long and hard frost. 7-10 days wouldn't be problem, but full month was too long.

-10 C is nothing for these colchicums. The main reason, in my opinion, is keeping the soil wet (watering during winter perid). My experience shows that in this case even extremely hardy bulbs can die even under the temperature +3 - +5 C.

Even warmer then here ..........so temperature drop during night can't be the trigger for flowering in this case ...

But it keeps me thinking ....what is the trigger to wake up al those bulbs ....

Thanks Franz ! Indeed he is not that hardy .........but I like this plant so much . I did see your plant on this forum some years ago and I did admire this plant  ....
We did see them flowering in the wild in Rhodos . The leaves are even not bad , they have a very undulate appearance....

Wonderful the Colchicum variegatum. Unfortunately my never blooms!

I struggle with this problem too Eberhard . I have also bulbs that don't flower ...This summer I bought a new one (from another supplier ...)and this is the one I showed on the forum.
I have some seedlings to and I am curious what they wil do in the future.

I did see them growing in Chios , Turkey and flowering in Kos and Rhodos . On the place we found them in Kos it was really hot ! They where growing in a kind of pure sand on a very hot place . Not any shadow at al .It was amazing.
On Rhodos they where growing on very warm places too on a hil. But overthere  also , some where growing in the clearings of pinewoods .
I think they need a very warm and very dry summer rest . But in my greenhouse this is not the problem. So there must be another trigger .....

In my humble opinion, the best form of C autumnale is 'Nancy Lindsay'.  It usually starts with me in late August, this year presumably because August was relatively dry, it is late and only just getting going now.  I started with 2 corms 10 years ago, now I have 3 big clumps.

Colchicum byzantinum 'Innocence' - white flowers with just a tiny bit of pink at the tip of each petal.  This started also with 2 corms 10 years ago, and has only multiplied to this extent.  Oddly, one corm at the far left reverted to pink some years ago, and this year another flower (back left in group) has a pink patch on one petal.

'Nancy Lindsay' is indeed very lovely - that transition from the pale lower tube up  through to  the darker floral base and throat is most attractive.

What an unusual rare display and beauty - like a crocus meadow :o 8) 8) 8)

I wonder if the meadow is utilized by a farmer? Certainly not !!!
The colchicums are the most unpleased weeds for farmers due being poisonous in all parts of the plant and harmful for most working animals/humans too.
The poison 'colchicine' is not degraded by drying or silage. Once absorbed it egests in the milk, too.

In order to eradict the colchicum population it is recommended to some sources to cut the meadow 3 times frequently through the early season and if not sufficient run flat the meadow with a heavy roller! The most effective method ist to use a roller with long spikes to sting the bulbs...

It is an example of the conflict of a save food chain and nature protection... :-\

Adult & experienced cattle and horses don't eat it as a rule. The risk of poisoning is higher for young, unexperienced animals and by feeding colchicum leaves and seed in hay. Sheep and goats seem to be less sensitive and can eat higher amounts of colchicums without an visible effect but they egest the poison via the milk... Especial hobby horse & pony keepers fear a poisoning.

Fermi, yes it is cute - only 4 cm from petal tip to petal tip. It loves a hot bake so I think it will thrive by you. If I get seeds, I will reserve some for you.

Look at last week's Bulb Log ::)

I don't think it is a good idea to replant them when they have roots. Unlike fritillarias, their roots don't form secondary roots (i.e. don't recover) when damaged. Doing so you will never get large-sized replacement bulbs the following year. Though if the roots are very short and if the replanting is done very carefully without damage, it will work.

Clearly, if there is as much root growth as Mark shows in that photo, then one would not disturb them . Ian made the point at at the stage where there is very little root growth ( even though flowering may have started) that it was possible to do it at that stage.  Depends how fast into roots the plants are- which is why I advised checking!
Title: Re: Colchicum 2013

its possible the root growth is later in Scotland. My Colchicums in the garden are mostly over now while yours in the garden are looking great.

Well,at the Great Dixter Plant Fair, the Beth Chatto Nurseries stand was selling Colchicum speciosum 'Album' bare rooted bulbs in bud/flower, so they clearly think they can be moved at this time of year. I bought one, pictured below immediately after planting, so we will see how it does.

By bare root I assume you mean dry bulbs? I guess these were bought in from Dutch sellers and wont root until they feel moisture

This is another case, such bulbs can be even planted after flowering. They root normally and give good harvest the following year.

No, bulbs with roots in a large tray with moist compost around them.

No, there was a tangled mass of roots which I carefully spread out in a large hole before backfilling. Here it is less than 48 hours after planting. Also Colchicum speciosum looking good in the autumn sunlight, and Colchicum 'Waterlily'.

This fall a multi-petaled colchicum appeared a few feet away from 'Waterlily'.  I am concerned because some of its petals were streaky -- rosy lavender on the inside but white on the tips.  Other petals were either all white or all lavender.  Is this a sign of the "Meadow Saffron Breaking Virus" I read about on the web?  Like others, I have always assumed colchicums weren't likely to get viruses.

Thank you for any help you can give.

I'm not clued up on that virus, Claire, other than reading some items online - so I cannot say if that is what is affecting  your plants -  has anyone else more experience/ photos?

A biggish pot of Colchicum cupanii SL482. Obtained as a single bulb from Monocot Nursery around 15 years ago.

Slightly past its best today but wide open in the sun and has a wonderful honey scent.

It usually flowers late October and (frustratingly) misses the Ponteland show by about two weeks!

Poul,
Your Colchicum is C. deicasnei which distribution is from S. Turkey down to North Israel.
C. trodii as it appear is endemic to the Toodos Mt. in Cyprus.
Title: Re: Colchicum 2013
Post by: pehe on November 20, 2013, 06:41:05 AM
Oron, I am no Colchicum expert,  and you may be right about deicasnei but I have read in Flora of Turkey that trodii grows in the Taurus mountains. And this article claims that it is found in Dörtyol in the eastern Turkey: 'The Flora of Dörtyol and Erzin Districts of Hatay Province in Turkey' (http://journals.tubitak.gov.tr/botany/issues/bot-98-22-2/bot-22-2-7-96044.pdf (http://journals.tubitak.gov.tr/botany/issues/bot-98-22-2/bot-22-2-7-96044.pdf))

In 2007 Karin Persson published her 'Nomenclatural synopsis of the genus Colchicum (Colchicaceae), with some new species and combinations', where she gives the distribution of these two species. I think Kew accepted it, based on this synopsis.

Thank you all for your reply.
Most of my plants looks exactly like this one, and  some of them are almost pure white, so the pictures do not convince me. To me trodii and decasnei look identical, can you tell me what the difference is? I will try and get hold of Karins article. Maybe that will give the answer.

Hi Poul ,

My remark was mainly based on the geografical situation ....Plants from Turkey are named as decaisnei and troodi is confined to Cyprus ....But nevertheless ...I grow both troodi from Cyprus and decaisnei from Turkey and as I remember wel there is a difference in appearrance ....This difference is mainly visible in the leafs .Maybe I have to take pictures from both when they have both leafs .

Anyhow ,this is what I found in a study .... Don't know if it is valuable to you or anyone ...


C. decaisnei is similar to C. troodii Steven and so differences between the 2 species are shown in Table 11.

Table 11. Comparison of morphological characteristics between C. decaisnei and C. troodii.

C. decaisnei :
Corm tunics  :membranous or subcoriaceous
Leaves :suberect to arcuate-procumbent linear-lanceolate to lanceolate or narrowly ovate channelled at least in lower
part margins slightly undulate
Perianth segments : linear to oblanceolate
Filament channels : puberulous at least on margins
Filaments :  4-12 (-14) mm
Capsule : oblong to elliptic acute or acuminate only ellipsoid rostrate

C. troodii
Corm tunics :papery
Leaves : erecto-patent ligulate flat hardly twisted
Perianth segments : narrowly oblong-lanceolate
Filament channels : glabrous
Filaments : 15-20 mm
Capsule : only ellipsoid rostrate

Cheers ,

Kris

Hi Kris,

Thank you very much. Your answer is most helpful!
I have not received Karin Perssons article yet but I have found some other information about troodi and decaisnei.
Earlier they have been regarded as one species, but some years ago the forms from Turkey has been renamed to decaisnei only leaving the plants from Cyprus as troodi. That explains why Flora of Turkey describes troodi as growing in Turkey.

Here are some pics of my different Colchicum decaisnei plants and their corms
