Thanks, Laaz, I'm definitely interested in new forms of trifoliate and will probably take you up on your offer for seeds.
Do you notice any other characteristics that differ from normal trifoliates with your tree?
I'm trying to find a couple of improved trifoliate cultivars, specifically poncirus+ but so far have not been successful finding any trifoliate cultivars with improved fruit here in the US. I think it could be a great starting point for breeding future cold hardy hybrids.
