Are these different in taste ? or is it the same fig? if not, what's the difference and which one taste better?
and why are those so expensive on ebay?

I believe Noir is French for Black......so same fig.   Also Blanc is French for White.

Dif figs, cost due to rare.

so what when is just labeled CdD alone? is that a totally different fig?
and which of those three taste better?

Just to follow up on Armando's question - are you asking about the difference between Col de Dame Noir (black) and Col de Dame Blanc (white)?  When I first red your post I thought you were asking about CdDN vs. Black Ischia!  I've heard that the taste is very similar for the noir and blanc (excellent) though Martin might disagree :)  The gris is supposed to be the most desirable of the three because it is a bit healthier and ripens fruits a bit earlier.  The challenge for these figs in the mid-atlantic/northeast is for them to have a long enough growing season with enough heat to properly ripen a good crop.

I assume CdD is lazy shorthand for the group of thee figs; I've never heard of a fig just called Col de Dame full stop.

I hear they are similar if not same tasting.
My CDDN grows very well and made a spare that grew 4ft last season but discarded due to parent doing so well in its 2nd growing season and producing some figs to sample.

CdD at USDA/UCD is actually CdDB. awesome fig. some members in north indicate issue growing them. but here, it grows very well. CdDN... didn't get to taste it this yr. good number of figs, but none ripened. did i mention weather sucked this yr?

Yup Pete you mentioned weather stunk many times this year and i agree it stunk here as well course we did not get constant rain but when we did get rain it was nasty.
Then some Nov. tornados here in our state recently and several of them in the western part of our county i reside in were confirmed.
5 - 6 folks perished in Illinois.

Farmers almanac predicts cold winter including our area and so far its holding true below normal Nov temps but
will seem nice come January !

Anyone have any idea which one UCD cole de dame is?

Blanc.

UCD CdD grows well for me.  No fruit yet, but nice tree.  Still young yet.  I seem to recall reading somewhere that these are actually Spanish.  I remember seeing a pic of someone's CdD Blanc growing on their rooftop there and it was huge and a beautiful looking tree.  I thought they said it was a Spanish variety.  Anyways, I can't speak to taste but seems like a nice tree!  I probably need a greenhouse before I'll be able to comment on its taste.

there is a fig with same name from spain. but from what i have read they are different. it's in different link on the forum. the spanish fig is more for drying? not sure.

Pete I made that mistake of confusing the two, Cuello de Dama is for drying but Coll de Dama is from Catalonia/Roussillon it is the same as Col de Dame that you have, also grown in Mallorca/Balearic Isles.

i need some of the cdd series, ponte tresa, rimada cutting, is there anybody have it?
