Mankato is an Americana plum from Mankato, Minnesota. S. D. Richardson of Winnebago City, Minnesota, introduced it in 1890. Early accounts said it was a seedling of German Prune crossed with a native plum. The South Dakota bulletin says the tree and fruit show no evidence of that ancestry and treats it as a pure Americana. It was important enough to appear among native plums in the station's 1902 and 1904 plates. The Minnesota State Horticultural Society later listed it as one of the plums most promising for trial in Minnesota. [S1]
The fruit was described as above medium to large, roundish, slightly oblique, and somewhat irregular. It had a slight depression at the apex and a wide, deep cavity. The skin was dark, dull red with a heavy light lilac bloom and many pale dots. The flesh was deep yellow and firm. The skin was sour but not strongly astringent, and the flavor was sweet. Overall quality was rated very good. The pit was semi free, roundish, and rather thick. [S1]
At the South Dakota station, Mankato ripened in early September. Recorded dates were September 4 in 1902, September 3 in 1903, and September 5 in 1904. Reports from other places put it earlier, from about August 15 to 28, depending on site and year. It was fairly productive, but the fruit was repeatedly said to rot on the tree and keep poorly. That limited its value despite its size and sweetness. [S1]
The trees grew very strongly and became large, with abundant dark green foliage. Station trees from the introducer, planted in 1898, were fairly productive. Norby later called the tree quite hardy, but he also reported that the fruit was much subject to rot and, in one year, of no special value. A Manitoba correspondence list includes Mankato among northern plantings, though the bulletin does not clearly show whether it ranked among the hardiest sorts there. [S1]
Historically, Mankato belongs to the group of prairie tested native plums judged as much by ripening season and reliability as by flavor. Its record is mixed: a handsome, sweet, fairly large Americana plum on a vigorous tree, but with its usefulness reduced by rot and short keeping quality. Its supposed German Prune parentage remains unsubstantiated in the source used here. [S1]
