Jose, the Red Himalayan variety I grow is from Brad who purchased it from Exotica nursery in San Diego. It seems to be a different version than the DMOR09 (Himalayan) mulberry that Marta sells on her website (reallygoodplants). So there may be four versions of a red long fruited mulberry that looks similar to each other. Once we grow all four variety then we should be able to tell if they are the same.
This seems to be a similar mystery as the long white fruited mulberry that has different variety names but seems to be the same mulberry (King Shatoot, White Shatoot, White Pakistan, Australian Green, Saharanpur Local). But I know for this long white fruited mulberry they are pretty much the same thing, I'm growing all of these varieties and I don't see any difference in the tree or fruit and the taste is the same, sweetest fruits, excellent taste.
