You have to keep the seedpots with colchicum seeds for at least several years as this photo shows.
One seed of Colchicum hungaricum germinated immediately (and now in flower) while others germinated last season and this season.

Another exciting issue of IRG is just online, which introduces new species to teach us more about the tremendous diversity of plants. 
Latvian,  Jānis  Ruksans works with his Ukranian colleague, Dimitri Zubov, to bring us a new Colchicum species. This is Colchicum kackarense, a new autumn-blooming species from the Kaçkar Mountains in north-eastern Turkey. 

Dr Zubov, as well as his work at the State Institute of Genetic and Regenerative Medicine of the National Academy of Medical Sciences of Ukraine, is a passionate and knowledgeable plantsman, especially famous for his work with bulbous plants.
This month we also learn about a new Leopoldia sp. from the Latvian Dr Janis Ruksans and the famous  Swedish plantsman, Henrik Zetterlund. New names are also proposed for seven Muscari as Leopoldia.
So, a typically international issue of IRG – with cooperation around the world to bring this to our readers.  We hope you enjoy it!

All my Colhicum are Fall Bloomers.  I have unsprouted seed of some Spring bloomers.

My Androcymbium and Wurmbea are in bud.

Colchicum 'Lilac Major' is a bulb I got many years ago from Mrs Ruth Tindale, but that doesn't appear to be a recognised name.
Some friends here think that it's a form of Colchicum byzantinum,

Colchicum season has started also here. A bit later than usually, but the first one for me is always 'William Dykes'.
It increases well and I have it now in several places. It seems to be sterile because I have never gotten seeds from it.
'World Champion's Cup' planted in August. I had one already last year, but it disappeared last winter, so I bought a new one, because I like this very much.

Stefan, 'Glory of Heemstede' is also my favourites, and it does well here, but is not yet up.
Dave, 'Disraeli' looks good! :)

So fresh & cool to see all these Colchicum after such warm and dry summer. I'll post this week end.

Colchicum speciosum 'Atrorubens'

This is very pretty! I had it once, but it vanished one winter. Now this year I ordered a new one from Sulev Savisaar, and just got email that parcel is in mail coming.  :)
I think I will plant it in dryer spot than where the vanished one was.

Colchicum feinbruniae grown from Oron Peri seed.
Tessalation is esp. visible at the start of the flowering
Plants can produce a few flowers per corm

Thanks, Maggi! This new discovery is certainly one of the most beautiful species!

I´m sorry for Your losses, Leena! Colchicum speciosum appears to be generally less hardy than others.

My favourite double is Colchicum autumnale ´Pleniflorum´, due to the refined arrangement of the tepals.

A species from from Georgia, lavishly setting seed and seeding around.

I suspected there might be differences in hardiness even in the common Colchicums. 'Atrorubens' was the only one I had lost before last winter, which was bad also for my Colchicums.
I am now over all the losses and enjoying the ones which are left, and planting more bulbs for next spring. :)

This is very pretty, and I like how you can combine them with Cyclamen.

Yann and Luc, I enjoy your pictures of species Colchicums, they wouldn't do here I think.

Some of my colchicums from the past two weeks time.
'Gracia' is a new one for me, planted in August. Pretty paler looking flowers.
Also 'Neptun' was a new one, and looks nice and early.
Colchicum x byzantinum 'Album' has done well, it has been here for 5 years I think.

Colchicums in the garden. I love how they add some lilac spots in autumn garden. They really make something in the garden this time of year.
My Colchicums are mostly garden hybrids. 'Glory of Heemstede' does very well here and I have now it in many places.

Post by: Leena on October 08, 2022, 05:08:28 PM
'Autumn Herald' has also been a good one for me and I have been able to divide it several times.
In the second picture in the background the yellow plant is Ranzania japonica which got a very good autumn colour this year.
Third picture there is C.autumnale in the middle, and the other ones are possibly 'Nancy Lindsay', I'm not certain.
Fourth picture is 'Rosy Dawn', picture today when it is at it's best.
Last picture is 'Violet Queen' or bought as such, but reading Colchicum book I have been wondering if it is 'Fellbrigg Violet'??
It has done well here, even last winter.

Since many years I suspected rodents to cause losses among my colchicum. This find on bare earth proves them to be the culprits.

Oh, that is bad news. We have also rodents here, some years more than in others, but there has been no damage to Colchicums, yet.
Title: Re: Colchicum 2022
Post by: Yann on November 17, 2022, 09:18:13 PM
Same here it started last Spring, never hard rodents problems before. Colchicum seems to taste good compared to crocus. I won't try a salad on my side :o

I've had slugs eat Colchicum corms, but never mammals.

The entire plant contains the alkaloid Colchicine which is very  toxic to humans.

Many mammals can eat things we dare not and vice a versa.
