It seems so Maggi , but that's dangerous to .....I stil remember previous year with the same situation and then suddenly winter came and killed many Colchicums here ! And they say winter is on his way to our country. Next weekend some frost ...hopefuly not so strong as previous year .

Nice early flowers, Kris :)
A Colchicum falcifolium flower opened today.

Nice early flowers, Kris :)
A Colchicum falcifolium flower opened today.
Thanks Tatsuo . I like this falcifolium to , just great when the flowers are laying on the soil like yours ...
Here the little nose of falcifolium is just above the soil .I hope he wil flowering soon ...
-
Stil in flower : Colchicum luteum 'Vahsh'
And just in flower : Colchicum doerfleri - very reliable and flowering each winter .
-
Colchicum falcifolium is still flowering.
-
Nice flowers Kris and Tatsuo,
1. A late flowering Colchicum psaridis
2. Colchicum luteum waiting for the sun to open
3. Colchicum vernum in the garden
Besides these, Colchicum troodi is still flowering both in the garden and under glass.

I like them both Oron , but the pink one is the one I would prefer .Thanks for sharing , this genus is a bit unknown ....so hopefully this postings change its status a bit .
-
Thanks Kris,
It is a good plant, only that has to be grown in dry conditions [maybe with your Lithops..] with plenty of sun, but very worthy as flowers last for many weeks!
-
On Thursday in the Aussies' company, I noticed a colchicum at my new place. The first of many I hope. I wonder if there will be snowdrops. I saw no sign of flowers or foliage in the springtime so perhaps not. :'(

Can anyone put me right with this please,... ??
Is this hybrid found naturally?? ???

The hybrid occurs in the wild Ron , that's what they told us ....But I don't know about the plant I showed because they tried to cross both in cultivation to ....
-
Not really wanting to be pedantic Kris..... but who are they???
-
See "Oakwood's" photo of the natural hybrid ( C. x albertii) here: http://www.srgc.net/forum/index.php?topic=8369.msg240448#msg240448 (http://www.srgc.net/forum/index.php?topic=8369.msg240448#msg240448)
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.
-
Not really wanting to be pedantic Kris..... but who are they???
I read that it was found by Arne Seisums ....like Maggi writes to . I think Janis write about it in one of his books but I am not sure about this ....Sometimes my memory ....

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?
-
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.

Colchicum luteum x kesselringii
Janis describes the two species growing in the same vicinity and the various forms of the natural hybrid, collected by Arne Seisums in "Buried Treasures" page 184
-
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'?
-
We lost our C. luteum and the hybrid in the cold winter of 2009(?) when the pots froze solid in the glasshouse
when the temps dropped dramatically for a long spell and the pots were not in a protected plunge - :'( :'(

Not something for a young man such as you to worry about, Kris!

Does the plant 'bulk up' well for you Kris?
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
-
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'.

Sorry to hear that you have had some problems like us, ebbie, with these lovely plants.

Still no sign of flowers on my Colchicum illyricus
Masses of Colchicum minutum out now - the best weed in one of my troughs

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.

Some of my Colchicum minutum open on a sunny day. Not so many flowers as last year so I must feed them

-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.

I take no chance with my Colchicum luteum. It's kept in my glasshouse where I can control both temperature and watering, but unfortunately not the light level.

This is a little colchicum I got from a Seedex as C. pusillum - which it isn't!
Any ideas? The foliage is fairly small as well the flowers stand only a couple of inches high and it has multiplied a little - I'm also finding what I think are seedlings but can't remember ever seeing a seed-pod.

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!

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 .....
-
I also think that there are clones that barely bloom. My not blooming when I let them baking in a greenhouse.
-
Franz and Kris, very nice Colchicum pics!
In my garden and green house they are flowering too.
The first one was Colchicum parnassicum in the middle of July, then C. graecum two weeks ago and yesterday C. variegatum.
This morning I saw C. montana has started flowering.

Please can someone id this Colchicum for me? I bought the corms from Hans Romer in Victoria in 2008 and this is the 1st flower. The only information he gave was "Collected Taurus Mts - unique long filaments" The photo shows these quite well.
Thanks,

Erle,
It is most probably C. cilicicum.

I do not know if this is a young Colchicum, or a small form.
Both plants are self-seedlings and 3cm high.

Hello John, sorry for the late answer ....It is Gentiana sino-ornata ‘Gorau Glas ‘.

Franz, the Colchicums in your meadow are very beautiful (as always!) Also nice to see that Sternbergia colchiciflora are growing there.
In my garden Colchicum montanum looks pretty now.

Another Colchicum observation. Maybe people know this already. When I plant Colchicums I always position the root end vertical. Repotting yesterday I discovered most reposition themselves so the root end is horizontal. In the second photo to can see where last years growth was a different direction than this years

Poul, stunning and vibrant color for the montanum

The photo doesn't do this flower justice. Colchicum asteranthum in all the years I have had it has never produced more than one flower and has never increased in number. Is this normal?
-
Are you sure that is Colchicum asteranthum, Mark ? Looks a bit on the large side and where are the leaves?
The description also mentions that it has soboliferous corms, so you'd expect increase.....

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 autumnale 'Nancy Lindsay'
-
And here, a large not quite sure hybrid, possibly 'Glory of Heemstede'
Colchicum hybrid
-
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.

Ian mentions this problem in this week's Bulb Log : http://www.srgc.org.uk/logs/logdir/2013Sep251380106127BULB_LOG_3913.pdf (http://www.srgc.org.uk/logs/logdir/2013Sep251380106127BULB_LOG_3913.pdf) -he thinks it's okay to split them even at this stage if it's done carefully........

Thanks Maggi. I haven't got round to looking at the Bulb Log yet.

Thanks for the tip Maggi .
Here two worlds ....the giant and little thumb .
C. 'Flamenco Dance' and C. parlatoris .

The Colchicums are still chugging along out on the coast. And still standing upright.

This one was obtained as 'Old Bones' - it's not, presumably because of the white mark. A quite tall variety.
Unfortunately this seems to have been muddled and is not 'Old Bones' at all which should be totally white. Thanks to Carole and Cliff for pointing this out.

Colchicum ?
Colchicum agrippinum
Colchicum speciosum
Colchicum speciosum album
Roma,
your colchicum ? is colchicum byzantinum

A friend of mine took these pictures of Colchicum autumnale in Carinthia. It is the southernmost province of Austria.

Oh my word! So many! I think the proper term is "locally plentiful" :o 8)
Thanks to you and your kind friend, Franz, for sharing these wonderful views.
-
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... :-\

Hi Armin,
Interesting information how to get rid of this 'weed' - from the farmers
point of view.
It seems cattle is able to avoid colchicums when grazing. Last week
I saw some cows on a pasture near Nettersheim/Eifel togehter with
hundreds of flowering plants.

Amazing C. autumnale that Franz showed us ! Thanks for sharing .
Interesting remarks from Armin and Gerd. Never looked at it in that way ....
Here Colchicum tenorii in the garden . I can recommanded it for rockgardeners because it is a bit smaller (see the difference with autumnale on one of the pictures)The flowers are more delicate.
I used to grow it in pots but now it is in the garden for two years and it seems hardy enough here.
-
The tiny Colchicum filifolium is flowering now
-
That's a little cutie, Poul,
How wide is it from petal-tip to petal-tip?
It's one I'll have to look out for on the seed lists!

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.

I don't think Colchicums can be divided now but will check tomorrow by looking at those growing in pots outside. I think from memory roots are developed too much.

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.
-
The proof that Colchicums can not be lifted and moved at this time of year. Whats not obvious from the photo are the mass of roots through the planting mix
-
In my experience the best time to move Colchicums is as soon as the old leaves are cut away
-
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!
-
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'.

Does anyone grow/know anything about Colchicum figlalii?

I know nothing apart from it having a stated distribution in S. W. Turkey and these links ( none of which lead to anything freely available!) -

Thanks. There is a picture on Wikipedia, it seems to be growing in water.

A dramatic photo- though I doubt it spends much time under such conditions.
I see Henrik Zetterlund shows it growing happily in a pot at Gothenberg Bot. Gdn.:

Colchicum bivonae today.
-
For the first time since getting my C. variegatum, 2006, it has more than one flower and bulb
-
Is it possible, that this is C. baytopiorum?
It is the only label of the genus neaby.
-
introducing my colchicums: the giant and a waterlily, all the others I tried have sadly perished.. :'(

Colchicum cupanii
-
Superb!
-
Excellent. Never seen such a pot...
-
Thank you Ralph and Herbert it has done very well this year
-
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.

Hi Ian so nice pot of cupanii ! i lost it in winter 2011-12

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?

after 8 years after sowing, first bloom of Colchicum longifolium with nice white mark at the apex of tepal. It is always exciting to see the first time flowers

Congratuations Do; very satisfying from seed.

It's worth the long wait. A very nice species.

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.
-
That's a fantastic pot full. Mine finished flowering weeks ago. Is this form always late? My plants were in full flower at the end of September

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

Colchicum troodi, I believe (collected at 400m in the Taurus mountains, Turkey)
Colchicum psaridis

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.
-
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.
Poul

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 ,

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

Colchicum
coustieri cousturieri from seed collected on a small island south of crete is flowering now - this name is now synonym for Colchicum cupanii ssp cupanii - I keep them separate as it is a much shorter plant here than other cupanii I grow.

It is a very beautiful plant Hans ! I think it is good to separate them , the neat and compact growth is a good characteristic.

Thanks Kris, glad you like it!
Thanks Maggi for correcting the name - written it twice and both times wrong, not bad... :P ;)
