Norby No. 51 was a named seedling plum reported by A. Norby of Madison, South Dakota. Norby was raising many plum seedlings and described this selection to the South Dakota Horticultural Society in 1902. The surviving description presents it less as a formally released variety and more as a promising grower raised plum worth notice and imitation. Norby mentioned it while urging others to save pits from the best plums and raise new fruiting seedlings of their own. [S1]
The fruit was nearly round, about 1 3/8 by 1 7/16 inches, red, and covered with a white bloom. Norby called it beautiful. All of the fruit was ripe by September 2. It also had practical merit: it hung on the tree for about a week after coloring, kept well after picking, did not crack, and in that report was said to escape injury from gouger and curculio. [S1]
The tree was described as small and still young. It bore its first fruit that season and carried only a small crop. That makes the record useful but limited: the bulletin preserves an early fruiting note, not a long trial history. No parentage is given, and the page places Norby No. 51 within a broader South Dakota tradition of selecting hardy seedling plums from cultivated orchards, not within a named breeding program. [S1]
For Pomologica, Norby No. 51 is notable as a glimpse of early prairie plum selection work at the grower level. It shows that local orchardists were not just planting named varieties. They were also raising, judging, and naming seedlings that might better suit their region. [S1]
