Nazarti and Nazareth are the same variety?
I know the Nazareth, i have a small plant.
This variety was imported in Europe in Spain from Israel for the early breba crop; it's a San Pedro type, the second crop is less important (this is what i read, mine hasn't fruited yet).
I don't have informations about hardiness, it's a middle eastern variety, i think that will not have to overcome harsh winters.
