I have a small Smith, and after reading of the similarity with TXBA1, I compared the two. They sure enough have the same leaf shape, though my plants have not produced figs to compare. My TXBA1 came from EL and has been stagnant for 3 or 4 years, until now, after planting in the ground. Now it is growing vigorously, but no sign of figs at all. I hope it is hardy in Zone 7, because I think it was listed as such by EL.
