Pino, I will probably plant it in the ground. I have the space now to put pretty much all my figs in the ground. I will still keep some in containers (San Pedro varieties and more cold-sensitive main crop varieties) but most will be transplanted into an orchard. Another nice thing about Atreano is it is both a large fig and relatively early which is not a common combination.
Cuttings for this variety came to me from BronxFigs who called it Atreano Gold. He got it from Zaino's nursery on Long Island and, as you suggested, I think they called it "Atreano Gold". We suspect they got it from Belleclare nursery who probably got it from Mathies.
