Worth trying the street markets in Geneva, depending where you live:

Tuesdays in Paquis: Market selling fruit, vegetables and manufactured goods. From 06:30 to 13:00 at Place de la Navigation or
Plainpalais: Local market for fruit, vegetables and manufactured goods. From 06:30 to 13:00 at Plaine de Plainpalais or
St Jean: Fruit and vegetable market from 08:00 to 13:00 at Rue Bleuet (also on Thursday)

Saturdays in Carouge: General produce market from 06:30 to 14:00 at Place du Marché

Sundays in Plainpalais: Local market for fruit, vegetables and manufactured goods. From 06:30 to 13:00 at Plaine de Plainpalais

Kale is also available on occasion on some street market shelvess in small villages on french frontally zone like Gaillard and Ville la Grand.

In addition to Milord's suggestions, you can try the markets in Divonne (Sunday mornings) and Ferney (Saturday mornings). 

go try some asian stores. They have alot of cabbage types.

You might beable to replace Kale with Swiss Chard. Its similiar and very very good for you.

Maybe also try Manor

Thank you guys for the tips!
I do have the Farmers' Market at Rive under my nose… ; ) and had looked at Plainpalais market in the past.
I am waiting for a call back from a farmer in Vaud, will keep you posted.
And for the Swiss chard which I use to sub the kale, here is a nice recipe: https://www.facebook.com/INNERCITYOGA#!/photo.php?fbid=10151224093254141&set=a.79330939140.81692.18746799140&type=1&theater&notif_t=like

Carrefour (Ferney).... Im sure Ive seen it there in season.

which Coop Mimi_crobe?

I'm going there this afternoon so I'll have a look. I'll try not to buy everything myself.

Kale is less known in the french speaking areas - there is an article about LE kale in Elle France, bringing it out as the new essential food…

After talking with several farmers, I learned that they produce small quantities only and it is a veggie which was almost forgotten about. It seems they sow it in June and harvest after the first frosty nights. They say harvesting it before the frost does not bring out the best taste; what brings me to the fact that in California (been living for too long there) - How is it possible it tastes so great there - all year round?

One of the places where we could hopefully find it is the Ferme de Budé www.ferme-de-bude.ch, but they are closed for winter break until the 18 january.

More info to come.

Manor Food in Chavannes said they would start stocking it this year (no specific date).

I changed my plans and wasn't able to go to Coop Blandonnet, but I can confirm that kale is not available at Carrefour in Ferney.

I am so glad that you posted this..  I have been looking for it for three years here and have never seen it.  I brought some seeds back with me this summer from California but didn't get to plant the garden this year.   Please keep us posted on when and where it is sold.  I am in Vaud not far from Gland. But I will go anywhere to get it.  It had been the staple of my diet, in juices and smoothies and cooked when living in California.  It is the number one most nutrient rich food! I really miss it.  

Friends!
One of my students found kale at Manor! Run, run, run, grab as fast as you can
Called choux plumes.

And also here is a website with organic kale: http://www1.vitaverdura.ch/produits/show/id_products_infos/643

And lastly I found kale at the veggie garden in Prangins National Museum - probably the not most legal way to go…

Thank you SOOOOOOOOO much for posting this!  At which Manor was the Kale sighting? I will be running!   

Hi, my student found it at Manor By the trainstation, enjoy

For any fans of Curly Kale in Lausanne......

I've been buying it for a couple of years in Lausanne at the twice weekly market - it's sold from the organic stall outside Zara, when it is in season..

By the way, the first picture posted was not Kale, but Cavolo Nero cabbage.
Kale was planted in all the many parks in Lausanne last year, and there might still be some.

I took some (along with some flat-leaf parsley) from the garden behind the Casino de Montbenon. 

I figure, if they're going to have a permaculture theme, a bit of responsible trimming is to be encouraged.

Oops... Never knew cavolo nero was a kale cultivar.
Bums. 

Try Botanic Bio Market, Gaillard, FR, 10 min from Geneva. I found it there though the choice always depends on the season.

Hi all. I spoke to the folks at Manor Geneva and they said that they stocked kale as an experiment in late January (imported from Holland!) and they threw 95% of it away. He said that it wasn't likely that they would choose to stock it anytime soon.

No joy either at the Sunday market in Plainpalais today.

Has anyone had any success??

MIGROS should also have them. Maybe in the the largest shops (Balexert, Vibert ), as it appears in their cooking magazine:

http://www.saison.ch/fr/magazine/produit-de-la-saison/chou-plume/

Otherwise, buy seeds ...

http://zollinger-samen.ch/fr/catalog/1/products/1120-lerchenzunge

I've been looking for that, too, but didn't succeed. I finally imported (a high quality) canned version from Germany. You can order it from amazon: http://www.amazon.de/Heinrich-L%C3%BCders-Gr%C3%BCnkohl-800-GR/dp/B009GEYWM8/ref=sr_1_3?ie=UTF8&qid=1363091319&sr=8-3

After the order I found that a few allotments in Vernier close to the migros there grow some. Maybe you can ask them if they sell some to you.

Sometimes ( If I am not wrong ) they are using some varieties as a decor plant in the pots in the center :D ....but that one is probably a very chemical one. Best is to buy organic seeds ( i am sure in organic shops as Bio Frais in St. Julien they should have ) and grow anywhere it gets :)

I saw kale at Manor on Friday and went back today to buy some but it - was - all - gone! Did you guys corner the market on kale? BTW, they called it Kalé.

I have seen in on two stalls in Lausanne market- one stall holder told me it is called  chou plumé.one stall is outside Zara and the other is next to the fountain by the musical clock in Place de la Palud

Update for this year: At least before christmas I saw it on the market in Rive on Saturdays, the vendor is close to the parking garage entry (Benoit?).  He gets it from Basel and said that he will be selling it as long as his supplier delivers it.

Kale can be found at Place de Navigation market on Tuesdays & Fridays form about 7:30 to 13:30

Enjoy!

I found it in Manor Chavannes
