I asked about some Morus Nigra I am growing on this fruit reddit and they said Pakistan Red will not grow in my zone (Zone 5b). I found a website that goes by Paradise Nursery and that state the zone for their White Pakistan Saharanpur is zone 4 which is 10 degrees hardier than my zone. The ones that state Pakistan white Shatoot say zone 9 though. I am wondering if it will grow in my zone and if they are the same plant as both are named White Pakistan.
from what ive read the only mulberries to survive and grow in the colder zones z4/5 are pure M. albas or illinois everbearring which is M. alba/ rubus cross.
