Hi Martin - The Sal's fig came originally from Edible Landscaping. Mike, the owner of EL, saw how similar his Sal's and Hardy Chicago looked and decided to lump them together and now sells them both as Hardy Chicago. There's a lengthy tread on the GW Fig Forum discussing it: http://forums.gardenweb.com/forums/load/fig/msg101415465988.html
(You've made posts to this thread yourself and mentioned that you have Sal's from EL)
Here what I have in my variety notes regarding this Sal's variety:
A tasty fig that does well on the east coast; similar to Hardy Chicago, but more productive. Mine originated from Edible Landscaping Nursery, which now considers it to be identical to Hardy Chicago. I disagree based on my own observations -- also, preliminary DNA testing by the National Germplasm Repository at Davis indicates that Sal's is closely related to HC, but not the same. Research by Byron Wiley indicates that Paul Traceski obtained this fig many years ago from a fellow named Sal in Huntington Station, Long Island. Paul gave the fig to Belleclare Nursery who added it to their inventory as #39. He also gave one to Hanc Matthies who in turn passed it on to Edible Landscaping. Note also that the UC-Davis DFIC 243 originates ultimately back through Edible Landscaping, and is not Sal's Corleone (BC #31).
