Steve:
The light makes it look so much alive. This is a very floriferous Colchicum. Looks like 4-5 blooms per bulb.
-
Thanks Arnold.
Sadly this represents no great skill on my part -my clone is quite floriferous and vigorous. I got it from Frank Schmidt of Floralpin (www.floralpin.de (http://www.floralpin.de)). Frank produces some superb plants -even his commoner species have that extra quality not found in other suppliers.

I've just been delighted by this shot of a glorious combination of Colchicum szovitsii and Scilla armena
pictured in Armenia by Tamar Galstyan from Facebook. What a fabulous sight!

Ooh heaven is a place on earth...
-
I agree, Tatsuo - the delicate colour combinations is especially pretty. What a place to see!!
-
A loss of sight, like that, it's a great show

Just what I needed to see this morning - thank you Maggi!
-
Flowering with me for the first time is Bulbocodium vernum, beautiful little pink flowers.
-
The autumn species are flowering here!
Colchicum ? cilicium with sempervivums
A different cultivar, possibly the one being sold here as C.byzantinum
One raised from seed as a larger species but it is too small to be that!
cheers
fermi

Nice, John and Fermi!
And about that wonderful field of Colchicum and Scilla, it reminds me of the recent On Being podcast: in it, a botanist explains why goldenrod and purple asters flourish best when they grow together. Applicable here, too, perhaps.

Two days later and the Colchicum (maybe) cilicium is in full flower!
And a couple of small flowers up on Colchicum neapolitanum (?macranthum?)
cheers
fermi
-
A pale form of Colchicum cilicium is now in bloom
cheers
fermi

I've been feeding my Colchicum bulbs with a blend of organic materials. Alfalfa meal, kelp meal, three different forms of calcium, feather meal and ground black rock phosphate.
These are the largest Colchicum leaves I've seen.
-
Colchicum cupanii which I got from Jon (Mini Bulb Lover) - he originally got it as C. psaridis but it was corrected by Otto!
cheers
fermi
-
From the garden today Colchicum cupanii. Bulbs kindly given to me by Hubi many years ago.
-
That's a lovely one David, and enjoying the Devon sunshine. None up here yet.
Tessellated like that, could it be C. x agrippinum?
-

Not C. cupanii David. Look at the photo with a typical flower.
Seems to be C. aggripinum indeed.
-
Colchicum sanguicolle from Turkey.
-
Thanks Ashley and Luc, x agrippinum it should be.
-
Cleaned up the dry gravel garden today. Very happy to see here the first signs of autumn.
Colchicum x agrippinum
-
Everything looking so neat, Ruben!
-
But its not always so neat Maggy. the dark leaved oxalis loves my garden LOL
-
Oh my! Yes we know these oxalis only too well!
-
Can anyone identify this Colchicum,? I have lost the label.
First pic in sunshine, the second one in shade.
Found the label, Colchicum neapolitanum var macranthum.
-
Colchicum alpinum
-
Colchicum x agrippinum in full flower
-
Colchicum x agrippinum in the shade

All autumn crocus growing in my lawn.
C. byzantinum Innocence + C. speciosum
C. speciosum
C. speciosum + Sternbergia lutea
big and small
C. agripinum
-
Colchicum atropurpureum
I bought a bulb from Paul Christian a long time ago. The flowers were always streaky though the leaves looked ok and it grew and increased. It has been seeding around and the seedlings look fine so I discarded the old bulbs this year. the pics do not do justice to the rich purple colour.
-
Colchicum 'Jochim Hof'
Colchicum bowlesianum
Colchicum cilicicum x cedric morris
Colchicum 'Flamenco Dance'
-
really nice set, bowlesianum is quiet pale, is it an Apollo hybrid?
-
My colchicum "collection" is a mix of species, hybrids, and unnamed seedlings (that are most likely C. speciosum). Here is a sample.
- C. 'Nancy Lindsay', always the earliest, with a nice dark pink perianth
- C. 'Glory of Heemstede'
- C. x agrippinum
- C. corsicum
-
Two more unknown colchicums.
-
I almost forgot the showiest: 'The Giant'
-
Here's another unknown.
Labels long gone but bulbs remain.
Could be a "Giant" as well.
Heavy tessellation as well.
-
Colchicum 'Jenny Robinson'.
-
This tiny thing came as Colchicum psardis.
-
Colchicum cilicium 'Purpureum'.
-
Colchicum Waterlily
Colchicum cilicicum akseki
-
It always gives me such pleasure to see your bulbs looking so good and neat, Franz. The Vienna sunshine keeps them in better shape than the Aberdeen climate, that's for sure. :)
-
Colchicum cilicicum akseki
:o :o :o
Amazing, Franz!
-
I looked at all September Cochicums this evening - they are all splendid, especially with the sun shining on them :)
-
Colchicum 'The Giant', Colchicum 'Waterlily', Colchicum x aggripinum, Colchicum autumnale 'Album'.

A phylogenetic analysis of the genus Colchicum L. (Colchicaceae) based on sequences from six plastid regions

Abstract:
A phylogenetic analysis of the genus Colchicum (including Bulbocodium and Merendera) is presented. The phylogeny includes all but four of the 100 species and all subspecies currently recognized in the genus, two insufficiently known species (C. mirzoevae, C. stenopetalum), and one cultivated specimen (C. laetum hort.) probably of hybrid origin. The analysis is based on 292 parsimony-informative characters derived from nucleotide sequences from six plastid regions (trnL intron, trnL-trnF IGS, trnY-trnD IGS, trnH-psbA IGS, atpB-rbcL IGS, rps16 intron) and 33 morphological, life history, and chromosomal characters. The genus Colchicum is strongly supported as monophyletic. The morphological data are considerably more homoplasious than the molecular characters, but provide added resolution to the trees derived from a combined analysis. The phylogenetic hypothesis is largely in conflict with the subgenera and sections recognized by Stefanov, and agrees better with some of the informal species groups defined by Persson in earlier publications. Additional data will be needed to resolve all relationships.

Abstract
The lily family Colchicaceae consists of geophytic herbs distributed on all continents except the Neotropics. It is particularly diverse in southern Africa, where 80 of the 270 species occur. Colchicaceae exhibit a wide range of ploidy levels, from 2n = 14 to 2n = 216. To understand where and how this cytogenetic diversity arose, we generated multilocus phylogenies of the Colchicaceae and the Colchicum clade that respectively included 85 or 137 species plus relevant outgroups. To infer the kinds of events that could explain the observed numbers in the living species (dysploidy, polyploidization, or demi-duplication, i.e. fusion of gametes of different ploidy), we compared a series of likelihood models on phylograms, penalized likelihood ultrametric trees, and relaxed clock chronograms that contained the 58 or 112 species with published chromosome counts. While such models involve simplification and cannot address the processes behind chromosomal rearrangements, they can help frame questions about the direction of change in chromosome numbers in well-sampled groups. The results suggest that dysploidy played a large role in the Colchicaceae, with the exception of Colchicum itself for which we inferred frequent demi-duplication. While it is known that triploids facilitate the fixation of tetraploidy and that plant species often include individuals of odd ploidy level (triploids, pentaploids), we hesitate to accept the phylogenetically inferred scenario without molecular-cytogenetic work and data from experimental hybridizations.

Colchicum cilicicum var. purpureum
-
Charming photo with a pollinator, Thomas.
-
A mystery Colchicum. I will have to sit down with the books tonight to try to identify it. The leaves belong to other species.
-
Colchicum pannonicum.
-
Matt : pusillum? does it has pinky petals once opened?
if not then it could be hungaricum, do you know where it was sourced?
-
Matt : pusillum?
That is my gut feeling just looking at it, but I will key it out to check. Thanks Yann.
-
if not then it could be hungaricum, do you know where it was sourced?
It is pink,Yann, also flowering now and with yellow anthers so it couldn't be C.hungaricum.
-
The diminutive Colchicum troodii.
-
a nice one, flowering after the rain? here no sign of water :P
-
Very nice Ralph, can you indicate your source please?
-

It's actually raining here. Should be over there in a few days.

may be colchicum umbrosum

I'm starting to hate trying to build a collection of Colchicums. So many misnamed or bulbs supplied that are wrong
-
Mark, I agree.
I stopped trying to keep labels in the correct place.
A rose by any other...............
-

I guess it is all to do with provenance as is the case with so many bulbs. Very frustrating though I have one which I thought was 'Old Bones' until I was put right by Rod Leeds and John Morley. Apparently the tube should not be green at all :-X
-
If only "provenance" were the whole answer to such problems. Too often it is not! :-\
-
Colchicum tenorii, Colchicum speciosum 'Album', Colchicum speciosum, Colchicum autumnale 'Album'. Allegedly.
-

I understand you very well, when I have got seeds like "Colchicum triphyllum" that flowers in autumn or C. cupanii that doesn't look like cupanii.
If anybody knows the names I would be happy. Maybe the last three are the same species.
-
It is easier, when you have collected seeds and it turned out to be C. variegatum or when you know the origin of the seed/bulbs.
-
Here just another Colchicum cretense whith nice colouring and C. baytopiorum.
-
Colchicum cupanii, a really nice specie
-
What colour is the tube of 'Old Bones'?
-
I got misnamed Colchicums this year and last from the same UK grower/seller. Another person got misnamed bulbs this year from the same supplier. S/he should be very reliable but proving not to be
-
Colchicum montanum, from a seed packet "Crocus serotinus ssp. salzmannii, JJA 352.006" ;D
-
The Colchicum season goes on and more and more species come into flower or towards its end.
-
:o you have such a nice collection Stefan! Superb
-
4 years ago I bought Colchicum illyricum ex Drake. It has taken the bulbs four years to get to flowering size
According to the internet Colchicum illyricum is a syn of Colchicum fasiculare but Oron's photo looks nothing like mine. Does anyone else grow C. illyricum?
-
Colchicum cousturieri, syn. Colchicum cupanii, from Kurt Vickery.
-
Colchicum parlatoris from Kefallinia. Some but not all sepals are flexed at the tip. This seems to be constant as I observe it every year.
-
First time in flower is this plant. The seeds were from Pilous and he called it Merendera ex Ipati. Any idea what species it is?

Ipati in Greece you mean ?
Are you sure it's a merendera ? Only M. attica and M. sobolifera are in the Greek distribution maps.
-
I found this merendera near the road from Pol Sefid to Firouzkouh in Mazandaran Province in Iran.
I think it is merendera trigyna but a confirmation from someone else would be wellcome.
-
seems to be a very variable specie : http://www.vanherbaryum.yyu.edu.tr/flora/famgenustur/li/me/tri/index.htm (http://www.vanherbaryum.yyu.edu.tr/flora/famgenustur/li/me/tri/index.htm)
-
Sorry, it is from Igueti, Georgia, not Ipati, Greece. I am not sure wether the name is correct.
