I bet it was a tc (tissue culture), which often take 3+ years to start fruiting for most people based on what I've read here and elsewhere online. I've seen rare accounts (one?) of someone getting figs from a tc after one year, but that's definitely an exception.
I dug into the issue because my first three plants were tc's from Wellspring Gardens (Black Mission, Green Ischia, and LSU Purple), and they haven't fruited yet (they're just under 2 yrs old) despite being very big plants (5' x 5' bushes with 1"+ trunks). Meanwhile, the cuttings I've gotten from fruiting-age trees seem to readily fruit the first year even as small plants (this was my first winter doing cuttings, and several are already putting on fruit at under 1' tall).
Due to the night/day difference in my own experiences, I've developed a strong preference for cuttings and won't grow tc figs anymore unless it's the only way to get a particular variety.
