The #1 tuffest Fig Tree I have has to be " Stella" ...This last Winter we got to 7 degrees, for one night! All of my trees in the ground,was killed to the ground, Stella was the first to show any signs of life. Now, out of 30 figs in the ground,she has the most growth and the most beautiful! What I am trying to say is she is for sure"tuff" Get her, if you can find her! : )
