All the Calverts I have shows FMV. Calvert shows more FMV than others. However, they are growing. As to if they will keep on growing and provide edible fig remains to be seen. So far, there is a good indication that it will put on the figs. But, I'll have to wait a year or two to see what the figs will look and taste like.
By the way, all my cuttings show FMV, just not as bad as Calvert or Ischia Green.
