Trifoliate is not the same as triploid. A triploid has an extra set of chromosomes and is often sterile to the point it cannot be pollinated with traditional strains. Trifoliate plants will sometimes keep the trait, and sometimes they grow out of it. It’s not necessarily genetically “programmed” into them.
Wow that looks lush very nice, Ime the tri foliate grows out when they get older, I can't be absolutely certain but iirc the tri foliate didn't transfer to clones.
