C. kesselringii is a very beautiful Colchicum, John. One of my favorites, here they are just showing their noses.
Do you grow them outside without protection? You probably don't get a lot of rain in summer in Kansas?

Thank you Wim,Hagen,Hans.  Wim it is outside no protection. I also had C. luteum open the
first week & a half of Jan. but did not take a pic.  Here is a pic of the environment
of kesselringii.  And one of my corner lot in winter. There are 3 large beds and 3 medium
beds not seen in this view.

I can live with that statement Hans. This two are also some of my favorite Colchicums. Kesselringii also flowers here. At least the common form , have more forms of this one ...
Again could not resist to take some pictures .....  Also Colchicum robustum is almost in flower here...

Oh yes Angie .It is a dwarf but it also helps to keep it in good light and as cool as possible during wintertime. It is plunged outside in sandbed and gets no heat .Only some protection against to much winterwet . Next year I want to try it outside in the rockgarden ...
Have even some tighter forms here , but they are not in flower yet .

Post by: angie on January 17, 2012, 09:13:31 PM
I thought it was tiny as the gravel in the pot looked large to me. Now I think that is worth growing. I have some of the more common ones around the garden but this one is something special. Hope you post pictures when the others flower.
Will source this one out.
Thats whats great about this forum you see so much lovely plants and also get the information on how they are grown.

Am I alone in seeing very few flowers on my Colchicums in the garden.

The leaves are now coming through - a great relief as I thought I had lost them

Colchicum autumnale bloomed as normal in most clumps.

Colchicum variegatum appears to have been wiped out, but I was glad to see Colchicum sanguicolle appears to have survived but again without flowering
Title: Re: Colchicum 2012
Post by: PeterT on January 25, 2012, 10:54:55 PM
I had a lot of damage here too Art. Most have survived though. C 'falcifolium' is flowering well, serpentinum and diampolis only just survived. no flowers on luteum yet but the bulbs were fine... only one flower on what was a 4 inch pot full of mirzoviae but some similar ones are ok. Colchicum seeds from Jim Archibald are germinating well at the moment.

Do we need two different clones of C. kesselringii in order to set seed?
Title: Re: Colchicum 2012
Post by: wooden shoe on February 09, 2012, 08:51:51 PM
I'm not sure. I had little success with most Colchicums to set seed, and if they do you might overlook it easily. Last year I have had seed on a sole Colchicum hungaricum 'Velebit Star'. This was polinated using a brush for there are not much insects at this time of year. For others were I had success, I had more individuals, but I'm not sure if that were clones.
I would say it's not impossible, but I might be wrong. Anyway, cross pollination is usually more successfull.
Maybe other forumists might have pollen. I can't help you because my C. kesseliringii are just one year seedlings under a layer of snow now.

Title: Re: Colchicum 2012
Post by: Sinchets on February 26, 2012, 01:41:57 PM
Flowering now that the snow has melted is what I think is Colchicum cupanii. I was worried when they did not flower in autumn. Now I realise it was an effect of the long, dry autumn. Another plant flowered under the snow a few centimetres away.

Jan,

I've never seen Colchicum kesselringii colour forms like that.  WOW!!!!!!!  I have just purchased this species again, having lost it a few years ago.  Only a tiny bulb though, so it will still be a couple of years until flowering I think.  At least I have it again.  That dark striped one of yours is just amazing.  I didn't realise there were other colour forms at all until now.  Thanks so much for showing us.  8)

Great Colchicums.  I don't think I've seen half of those species before.  The bifolium looks like it has excellent width of petals and substance..... very nice.  I grow luteum and just recently purchase kesselringii again, but I've not seen the majority of the others you've shown.  I didn't realise there were so many spring flowering Colchicums.  :o  Thanks so much for showing us.

Post by: Janis Ruksans on April 01, 2012, 08:25:50 AM
Here still are blooming spring Colchicums
The first picture is of hybrid between C. keselringii x luteum, selected by Arnis and named 'Janis' at my 50th Anniversary
Follows two other siblings of it (I think they all were collected in Tadjikistan near Tovilj-Dara). They are known under name Colchicum albertii, too and Karin Person tends to regard them as species - result of past introgression from C. luteum into C. keselringii. So named "hybrid" is fertile and seedlings slightly varie from whitish yellow to light yellow but allways with yellow hint. They just this spring bloomed with me for the first time. By Karin Person artificial crosses between luteum and keselringii very rarely get some results. There are known only two reports about such cross. So I would tend to name this "hybrid" as C. albertii.
On next two pictures Colchicum keselringii - the first from Jan Jilek seeds as collected in Afganistan, on another mine own from Shing - N Tadjikistan. Both are very similar, but C. keselringii really is very variable.
And as last three are spring Colchicums from Turkey, just identified by Karin Person.
The first was collected at Gembos Yaila just on parcel where started building of new house - Cochicum szowitsii subsp. brachyphyllum - one of brightest and one of my favourites
Another is Colchicum serpentinum - another superb beauty. The pot was not replanted for 3 years, so very abbundant blooming.
The last is C. triphyllum - quite common species with large rounded flowers.

Between C. luteum and C. kesselringii?
I don't know. I cited Karin. I tried to cross them both ways but without success. C. albertii set seeds very well. Pollination were maid by bees, so I didn't know pollen parent. Both - keselringii and luteum set seeds, too but progeny allways looks as mother plant. All three species allways are placed side by side - so no problems for bees to crosspollinate them.

Kris and Peter, how is your experience growing C graecum outside? I have tried several times without any luck in a south facing raised bed. It didn't survived the winter. When I checked it in spring the bulb was attacked by rot. Now I grow it under glass, but there is no signs of it yet.

Colchicum bivonae Apollo is flowering now in the garden.

Hello Poul , it thrives better here outside then before in a pot in the greenhouse.The first two years I keep it in a pot in the greenhouse  , but under these circumstances it never flowers with me.So I changed my plans and I planted the bulb in my usual compost in a basket (the ones we use to grow plants in the pond)This basket I plunged in my peatgarden . There it stays the whole winter and it gets frost here (no snow this winter !) until minus 15 degrees ....For 14 days the garden was very frozen here ...In the spring , the leafs stil looks very good and I noticed almost no frostdamage.
We had a very cool and wet spring and summer here. The leafs stays very long on the plant ! Until for weeks ago it was stil in full leaf ....I was thinking  that it not lost his leafs this year ....but suddenly it did .I think it get really a boost and much energy from the old leafs ?My peatbed gets sun in summer from the morning until 14.00 hours in the afternoon. (east - northeast facing)In wintertime it gets almost no sun because the sun could not rise above the houses of the neighbours ....The compost of my peatbed is composed with leafmould ,bark,composted bark, peat and bit of loam .But the bulbs are planted in a basket that is filled with my usual bulbcompost .
Best regards and much success with this bulb-season...

Hello Kris,
Thank you for your detailed answer!
I have a peat bed very similar to the description of yours, so I think its worth trying to grow one of my Colchicum graecum there in the same way as you do. I will let you know the results.
I wish you success with your bulbs too.

Poul,
Mine is in a clay pot in a raised sand plunge, open to the rain, it has been awet summer here. I think that the texture of the compost is important, it should not get waterlogged.
Here, now flowering, is Colchicum feinbruniae from Jim Archibalds stock, in the same sand plunge.

Here, now flowering, is Colchicum feinbruniae from Jim Archibalds stock, in the same sand plunge.

Probably this one, Peter, from a collection by Bob and Rannveig?
314.250 : COLCHICUM FEINBRUNIAE Syria, near Laqlouq. Ex R.& R.Wallis 99-32. (A distinct, very attractive & floriferous, faintly tesselated, pink, medium-sized, autumn-flowering species, recently described & now introduced to cultivation. One of the first species to flower with us, usually appearing in mid-August.)

Colchicum byzantinum "Album" after a heavy storm.

A bit dirty, but beautiful anyway. I like the small hint of purple on the styles.

My colchicums like the fine weather we have in these days.

1. Colchicum davisii
2. Colchicum pannonicum
3. Colchicum hybrid
4. Colchicum bornmuelleri

Dirk, the shape of this flower is much more elegant than their daughters, C. agrippum, which is the only from this family, that I have. If you ever get seeds or spare bulbs of variegatum, I am ready for a swap.

A rather pale Colchicum (Merendera) filifolium has just opened.

I have been harvesting potatoes, and a few of them was eaten by small black slugs exactly as your corms. Normally these slugs are at the surface, but I think that they have found a path to the goodies where the stem once were.

Finally, some signs of autumn down here... still 29C.

First Colchicum to bloom in this region is C. tunicatum, a desert species that bloom while temperature is way above the 30c. It takes its name for the many layers of tunics that protect the bulb from desiccating.
And in the shade, C. decaisnei is just starting.

Hello,
Colchicum cupanii I think.
I had five plants, two were planted outside, three in my bulb frame. The two outside are in flower, the ones in the frame are dead ???
Some plants do not appreciate all the caring love I pour over them!

Snails seem to enjoy these cute flowers. They do not read books, so they do not know that they are poisonous!

Hi Angelo

They're small and fleeting in many cases, and so many have foliage that is so large and out of proportion (and gets in the way of everything else).  The foliage doesn't bother me at all, but I have heard a number of people lament it.  I love them, particularly some of the smaller species.

Nice Colchicum, Otto, quite distinct in the way the segments are overlapping. C. lusitanicum is quite widespread in Iberia and northern Italy. Unfortunately, the population I saw was only just coming into flower and there were only half a dozen or so in flower. Even here though the amount of tessellation varied somewhat. Good natural variation I'd say.

Post by: Oron Peri on November 28, 2012, 08:56:51 PM
Thanks Kris,
We have noticed similar behavior with C. stevenii and C. tunicatum, both species often produce only male flowers before finishing their blooming time, [meaning the last flowers of the season]
We haven't found an explanation for this phenomenon.

My theory is that when the plant has enough flowers which have been pollinated, in order to save energy, particularly in the desert, it ensures that no more pollination might occur, and to do so  it doesn't develop the style.

I think your plant is C. szovitsii subsp brachyphyllum [syn. C. brachyphyllum].
It is very difficult to have good results with this species as it grows in particular conditions: a long, dry , hot period of dormancy than cold, damp conditions during winter [often with snow]. Bulb is buried 30-40 cm deep in heavy soil.
I grow only one plant and it looks very similar to yours :-\

This is how it should look...
