Danish Damson Krueger is a domestica plum. It is recorded as a Danish introduction brought to Minnesota in the spring of 1834 by H. Knudson of Springfield. [S1] A South Dakota bulletin describes it as an old imported damson with a mixed reputation. A. Norby said it was "not truly hardy," but the same source also calls it the hardiest, most productive, and best of the domestica plums tried there. [S1]
The fruit is described as small, about three fourths of an inch in diameter, and blue or black in color. [S1] It colors early, ripens medium late, and hangs well on the tree instead of dropping quickly. [S1] The bulletin says it set a good crop and was fine for canning. This suggests its main value was for kitchen use rather than fresh dessert quality. [S1]
Its historical interest lies in the tension between European plum quality and prairie survival. As a named domestica plum imported from Denmark and tested in Upper Midwest conditions, it represents the long effort to see how far the classic European plum could be grown in colder continental districts. [S1] The hardiness evidence remains uncertain because the same source preserves both praise for its performance and a direct statement that it was not truly hardy. [S1]
