I agree with Brian. Those leaves don't look like the Ischia Black UCD leaves at all.... There an't too many folks that sell on eBay and also sell IB that I would trust. Those mentioned already by Vinny are 100% trusted. Herman was also selling IB last year and I think he is also legit (and his cuttings sold for between $60 and $100 apiece). There are a few others that offer them rarely but they are also good. There are many forum members that have the real deal but that don't offer them for sale but will consider trades and there are also very generous members that gift them outright or offer them at gift prices such as Karla's incredible offer. There are a few varieties that have cachet and are reputed to be awesome tasting as well, I think Ischia Black is one of those handful+   MHF varieties.

BROGIOTTO NERO
SYN: VIOLET DE SOLLIES, NERO
DESCRIPTION
[Translated] Large violet-black autumn fruits of dark-blue color, very good quality, but only in August ripely. Important sort for Gewerbsanbau in France and Italy, is however dependent with us on pot or winter garden culture, because the fruits in the garden mature too late. (066)

I purchased ischia black from Jon for 5 bucks this season. There is no need to spend a ton on them...

Hi Kelo,I would not take all the synonym links seriously as they are not authoritative or independent,it may just be that someone had a Nero or Brogiotto Nero etc labelled as Ischia Black.Im sure if you click through enough synonym links from any black fig you will end up eventually at a white fig.

Brogiotto Nero is definitely a stand alone variety not Ischia Black from what I've seen,but Violette de Sollies may be synonymous with Brogiotto Nero according to some ,Barnisotte(Noire) is just Brogiotto French(?) ,Nero is just Italian for any black fig.

Livetaswim,that was a bargain!,you should have bought the whole lot

Kelo,it definately is a mess,I do wonder if the USDA strain and the European one are the same,the Ischia figs are somewhat of an enigma.I do hope you manage to find a Black Ischia, which one is THE Black Ischia remains open to debate,probably the biggest and most contentious one ,always fun to watch though

Livetaswim you guys in the US are blessed to have guys like Jon,and many others,our sources over here are somewhat more limited

Was this your purchase? or did you buy from Jon off ebay?

That's not USDA UC DAVIS Ischia Black.
Jon also sells another fig  listed as Black Ischia "AD" that is not USDA UC DAVIS Ischia Black

I'm sorry to add more confusion but the one Jon sold as black Ischia is not the USDA strain . From what I know Jons black Ischia is called Black Ischia AD!. I know for a fact that some folks have been waiting nearly 4 years to get hold of the USDA strain. There is a reason why it's expensive, one being it's extremely difficult to propagate. Some members sold and later refunded the money further to finding out it's not the real deal. There is no alternative for the usda one and the key is to get the right one from the right person and not further investigating to figure out whether it's similar to some Fig X or not. Please watch Toms videos and you'll know why folks are mad about this one.

Is the non-UC Davis strain significantly different?

The UC Davis strain is heavily effected with FMV. It is probably going to be best grown on a healthy rootstock. It is extremely rare to find partly due to slow growth and rooting difficulty. There are phonies littered with different names that have originally been passed around as the real deal. It took me three times to get the real one. The others floating around are similar but more like VDB imo. If you are collecting figs the real deal Ischia Black is definitely one to add to the collection.

Brian, in that case this might not be a phony. According to multiple sources they are one and the same. I wasn't able to find anyone who had grown Blue Ischia next to UC Davis Black Ischia. Do you know anyone who has both for comparison? I am not a collector, just an eater, but interesting in the history of them. If you have the real UC Black Ischia, I would send you a cutting of the Blue I have to compare growth and fruit in the same location. 

Blue Ischia and Ischia Black are not supposed to be the same in spite of intense wishful thinking. Similarly Black Provence which was once being discussed as being the same as or not the same as Ischia Black, are not the same variety either.... You can get Black provence fairly cheaply too. The danger here is that someone thinking that they have the real Ischia Black further distributes that mis-named variety as the real thing and  confusion and mis-labeling become the order of the day.... Real Ischia Blacks are sometimes distributed by generous members for less than market but they know it and they will tell you what it is that they are giving you...  You can also get amazing prices for Ischia Black cuttings from dausername1 and others on ebay; good luck with those... I doubt that Jon purposely sold you those cuttings while attempting to mislead you that they are the UCD variety; your best bet if you want to make sure is ask jon and I am sure you will get an answer...

I had a package arrive today from Portugal (Portugal was in bold type so thought nothing of it and threw away the bag). On the plastic bag there was BM; I was expecting Black Mission because I stupidly forgot I had some already - 5 grade A painkillers are crap for the memory. The cuttings were being rehydrated and I remembered I had ordered Black Madeira.....the light bulb eventually went on in my brain and I checked the tracking code. Turns out the Black Missions labels I had written were for Black Madeiras; this doesn't help the madness, does it but it does show how things are easily and genuinely confused. I'd also, personally, like to kick the asses of the people knowingly selling fake Ischias...

How is Jon's Black/Blue Ischia AD different from the UC Davis strain? I have yet to see someone compare the two directly in the same location. The only thing I have heard about the UC strain is that it is heavily infected with FMV. Is the taste significantly superior to the AD or in any way different? From what I am reading it seems that nobody has compared the taste or growth. I have not yet seen the video referenced above.

EDIT: From searching in the forums, I found Harvey discussing the differences between IB from Encanto and IB from UCD and they were essentially the same to him. I would be interested in other inputs.
