their from visc and jordan of the island through kindseeds.the black has been around for sometime in BC,so it is stabalised,it is a very heavy stone im told,real couchlock.i think the black has had other names in the past but from what ive seen and from bc growers it is all a like more or less.but i had a god bud phenoe that leaned to the purple skunk which looks a lot like the black,but it was a good producer the leaves were so thick and black and leathery rubber.and it hit hard.it was a beutifull plant it really was.
