This will help . The first pictures are of the 1-3 pecan out of the catalog . Real height 7-9 inches. The next couple are the potted pecan. Real height 24" . That is a grafted variety Normal a selection from Normal IL . I would have loved another grafted pot grown variety for pollination but they had only Normal . So I settled for seedlings . Nut trees are seldom sold in pots around here and bare root ones are hard to start. The last picture is the English walnut height 36" . I only bought 1 so I will need a pollinator . I hope to graft pecan to hickory seedlings in the woods. English walnut to black walnut . These trees were too small to take scion wood from this year .
