Narrative

Southworth (PI 541350). Scionwood brought from near Duluth, Minnesota, by a Great Lakes captain sometime between 1900-10 and grafted on two trees at his home near Massena, N.Y. Introduced in 1968 by Fred L. Ashworth, St. Lawrence Nurseries, Heuvelton, N.Y. Brought to Ashworth's attention in 1967 by Frank Southworth of Massena, N.Y., present owner of the property. Parentage unknown. Fruit: medium large, as large as Bartlett; shaped like Duchesse d'Angouleme; skin green, rarely blushed; flesh has very little grit cells, flavor good, not as sweet as Bartlett; seeds per fruit average about three; ripens 20-30 Sept. in New York; some fire blight resistance. Tree: medium size; upright, vigorous; extremely hardy; productive; self-fertile. Original trees are still strong and vigorous, showing no sign of winter injury. -- Brooks and Olmo Register of Fruit and Nut Varieties.

The Southworth is possibly my best 'find' of any fruit genus thus far, as it fulfills more of real need than any of my others. I have grafted more of it than anything else this year. Two trees of this pear were grafted by a Great Lakes skipper about 1908. They have not winter killed since (winters to -45 F during that time). Nor has it blighted; and it bears fruit almost as good as those offered in the stores. It seems to bear from its own pollen. I surmise the captain learned of the pear from a Finn or Norwegian and arranged to have propagating wood sent or brought to him. His name -- I think -- was Benton; but the Southworths bought the place from him, and Frank, the second Southworth owner called it to my attention, so I named it Southworth. -- Fred L. Ashworth, Route 2, Heuvelton, New York. North American Pomona 9:20. October, 1969.
