One day I will find someone with a healthy Zingarella tree ,and get some cuttings,because the original tree in US,from where Richard Watts got the cuttings,was someone on the east coast,according to Richard Watts.
I am sure it was ,an Italian importation,and the tree is totally healthy,lacking FMV,and so hardy enough to grow here in NJ.
One thing is fact:The cultivar is well known in Italy,and very much appreciated,and planted,and that is Why the presenter of the Video stopped right by that tree to offer a sample,of ripe fruit.
