Great selection of trees, the nursery is a good 50+ miles northwest of downtown Chicago, out in the boonies. There are actual farms that far out.
He has some nice small affordable selections of recently propagated stock. His more mature stock, with several years, if not a decade or more of growth after propagation by grafting or cutting, the mature stock prices reflect the time required to bring these dwarfs up to size. Worth a trip to see.
