This family of American plums does well in the same districts as the Japanese varieties just dealt with, but has the advantage of being resistant to the fruit fly. The trees are usually more or less straggling growers, the fruit is of small size, but good for cooking or jam-making. One or more of the varieties of this plum are bad setters, though they blossom profusely, but this may be overcome either by working two varieties which bloom at the same time on to the same stock, or by planting varieties that bloom at the same time together, as the pollen from the one will set the fruit of the other. It is a good plum for home use or marketing, despite its small size, as it is easily grown, requires little attention, and is not over particular as to soil.
