Hi Greg, I appreciate you reaching out.
In my own garden I am selecting heavily for upland tuber production, in addition to seed production. I am still in an early stage of the project, so the best and most productive are the ones I feel inclined to hold onto.
That being said, my hopniss originates from a wild population down the street that is absolutely loaded down with seeds each fall. I can provide you seeds from this prolifically-seeding wild population.
