I agree with Gorgi- Sal's C relative. I'm curious to see how it does with humidity and rain. My Sal's C splits towards the end of season but I like it enough to put up with it. But there is no guarantee that what you have came directly from them. It just may be a cutting or plant from someone that had access to ones from Sicily and in relation may be the same one they had. Still cool to find though. I have an unknown from someone that's family came over from Italy and right now it's looking like Sal's EL/Gene and there are from CT. Will know more in a few years.
I wouldn't be surprised if you find more there in the V. Stream, North V. Stream, Malverne area. A lot of Italians and those that grew up in south Queens moved out that way from Ozone Park/Howard Beach. Even parts of Rockville Center and Franklin Square.
