After browsing the net for information about vendors it has been mentioned that it's a cool grower on several of the sites. Personally though (being a newbie and all), I have no idea.

Thanks for all that info Silken :) So coccinea is a no for this project.
We did do a rupiculous a few years ago (L.reginae) but there are plenty of others to choose from!

As for joining, you can always sign up, participate in the discussions if you want, and decide later if you get the plant or not.

Would anybody be interested in trying to grow Bulbophyllum ambrosia ?

It seems like listed from hot to cold and is claimed as easy grower, and this genus wasn't covered by previous projects.
It is available from Clouds in Canada at $25 for BS.
Sorry, if this is not good suggestion.

Found it at Großräschener Orchids for 19 EUR so it's available in Europe.

It is also available in USA from here:
Carolina Orchids - BULBO Data
But I am not sure what the word medium refers to :
medium seedling or medium sized plant in their case, because it doesn't say MS or medium seedling.

So far no luck at finding rupicolous Laelia here in Europe though. Has anyone else found it?

Another one that looks interesting is Jumellea comorensis :

Available in Canada at $30 from here:
Tropical Gardens Orchids
They say it is suitable for windowsill.

la cour des orchidees in France has some
L. bradei, L. reginae (just got some from them recently :biggrin:)

They seem to have a great choice of rupicolous here: http://www.orchideen.com/offer.htm
same store, different page:
Online-Shop

It doesn't seem to be available in Europe... :(
Has anyone else found it?

It is available from J & L Orchids in USA and Ecuagenera.
Both companies are coming to Canada in April.
Not sure about Europe.
