    I just purchased this plant today. I heard about it on the ATP podcast. I can't wait to see how they come out.
  • Posted by Bonehead (Planet Earth - Zone 8b) on May 12, 2015 2:24 PM concerning plant:
    This ripened well for me with good yield, but I found the flavor to be bland and a bit on the mushy side.
  • Posted by Newyorkrita (North Shore, Long Island, NY ) on Jul 31, 2015 7:12 PM concerning plant:
    This is my first year growing San Marzano. I simply had to try it because of the people recommending it in the Fruit and Veggies Forum. I compare it to Roma, maybe slightly larger but similar taste, at least when fresh. Very dry. No seeds. I will have to use these for stewed tomatoes this year and see how they turn out.

    In my opinion, they work well for fresh salsa if you mix them with some more juicy, slicer-type tomatoes.
