After a particularly mild night on New Year's Eve, it was a great surprise that suddenly a lot of bulbs came out of the ground. Almost out of nowhere to sudden bloom...A splash of sun on New Year's Day and therefore under enormous time pressure, due to a number of family parties that were still on the program, quickly went outside with the camera...
The first one is Crocus sieheanus . This Crocus is a remnant from the fantastic collection of Hendrik Van Bogaert.The label says :Çaykayak - 1650m .

After a short check of the pots, more flowers appeared. In the same color range but with a touch of black : Crocus gembosii 'Sunspot' .

IRG 157 January 2023
We have two articles this month, firstly from Jānis Rukšāns on a new crocus hybrid raised by Dirk Schnabel in Germany and secondly, a report from Panayoti Kelaidis on the Patagonian plants which are doing well in the Denver Botanic Garden.

In the afternoon, the sun shone and the temperature in the greenhouse reached + 9 C - the crocuses started to open their flowers and I, in turn, photographed them and also managed to examine some before they closed firmly again. It seems that it will be one of the earliest seasons and if the weather conditions do not change, it will be in full bloom already at the beginning of March, which I will, of course, report on.

Those are all stunning, Janis.
Sadly C. gembosii is not on our "Allowed list" to bring in as seed - if it was ever available. of course :o

Very exciting, I just noticed that my single plant of Crocus scharojanii flavus I self-pollinated last summer seems to be developing a seedpod.
-
Five years ago I planted two different C.tommasinianus but they look the same to me.
The one in the first picture should be 'Barr's Purple' and in the second picture 'Whitewell Purple'.
Third picture shows both.
How should they differ? If they are the same, which one are they? Or are they something else?

Leena, this is a question that has exercised forumists for ages!
Start reading here: https://www.srgc.org.uk/forum/index.php?topic=4369.msg139693#msg139693
Whitewell Purple has a dark tube. All yours have a white tube, so are probably Barrs Purple!
-
Maggi, thank you so much! I see that these two have been mixed up before. ::) Thanks for the link to the older discussion.
Yes, tubes in mine are white, so probably then 'Barr's Purple'. :)
Here are two other nice crocuses.
Crocus x leonidii 'Little Amber', I like this. :)
Crocus korolkowii 'Yellow Tiger'
-
a few Crocus nivalis from last sunday on Chelmos and Kyllini, GR. It was cold and late spring as all over the Balkans.

Autumn came and the autumn crocuses bloomed :)

Sorry Stefan - your image is not showing.
Is it visible now?

Is it visible now?
Yes, fine now - thank you!

Crocus sativus

Crocus melantherus are currently blooming in the garden. This species like sticky clay and lot of water during the growth periode. No doubt that the 380mm fallen the last 20 days were benefit for a lot of plants that suffered this summer.[attachimg=1][attachimg=2]

Yann,
Thank you for showing the photographs of this fine Crocus species and sharing some cultural information. It seems like it would be a fine species to grow in our California garden. I will see if I can find it here in the U.S.A. If one puts out the effort many things turn up close to home. :)
-
Yann, a beautiful crocus. :)
Here temperatures are so low that although autumn crocuses come up, they don't open.
Still, I like the most hardy ones. :)

Hi Leena,
I find a beauty in the unopened Crocus flowers just like I find the beauty in your garden despite, or maybe because of the character of your gardening climate. Here in Northern California, dealing with the 40 plus C temperatures and the months without precipitation each summer has its challenges. In many ways our gardening season ends with the summer heat/dry and returns with the autumn rains and cooler temperatures. I find a great deal of beauty in our hot dry season, that those in Northern Europe might consider dead, ugly, or a disaster. It seems like it is all ones perspective and like relativity it can all be correct.
Recently our weather here in interior Northern California has been “average”. We have had some rain, about average to date, some very cool weather, and some periods with much above average temperatures. There is no snow in the Sierra Nevada Mountains – this is unusual for this time of year. Currently there is a very strong El Niño in the Equatorial Pacific Ocean. Generally a strong El Niño is associated with high snow levels in the Sierra Nevada Mountains. The amount of precipitation this winter is on everyone’s mind. El Niño was associated with above average precipitation for California, however since ~ 2000 our climatic patterns have changed dramatically. We are in uncharted territory and many aspects of gardening have become very challenging in our area.

This photograph is of Crocus niveus blooming on 12 November 2022. This year the flower buds are just emerging from the ground. We got a good seed crop from this species for the first time last year. All the seed has been planted in hopes that we get some genetic recombination and can spread this species around in our garden. It certainly does well here.
Crocus kotschyanus and Crocus speciosus bloomed earlier this autumn. They have never set seeds. The Crocus speciosus were purchased as corms from a local nursery and are likely all the same clone. I have wondered if Crocus species are obligate outbreeders? I have never found the answer to this question. The Internet has not been helpful at all. I am sure that a botany professor at some university somewhere knows the answer to this question. Maybe some are obligate outbreeders, some are not. For me an important question with no easy answer.
Enjoy your gardening day! :)

Robert, you are right. :) And though I don't like winter, it would be as hard for me to live in as hot climate as what you have. I enjoy your pictures from the mountains where you go!

Leena,
Come to western Oregon. In the last decade: we have only had 137 days below freezing. Of those, few have been below 20F [-6.6 C] and none have been below 15 F [-9.4 C]. In summer we have had only 22 days above 90F [32.2 C]. Our average Summer temperatures range between 75 and 88 F [23.8 C- 31.1 C].

Marc, I think also Scotland would be perfect climate for me. :)
Well, four more months until first signs of spring hopefully here. :)
