According to the laminated certificate of authenticity received with related NA 84921 in 2017, 14 seedlings were obtained and grown by American Harvests, then were planted at Mt Cuba Center in Delaware. Those trees were then cloned by budding. A second plant, this accession, arrived in 2019 and was initially recorded as another plant of NA 84921; however, it was evidently donated by St. John's College, Annapolis, MD. It is presumed to have the same background otherwise. | 2137085 | NA 87816 |
