Damson

Prunus domestica subsp. insititia (PROO-nus doh-MESS-tik-a)

Family: Roseaceae Unknown Understory (15-40 ft)

The Damson plum tree is a variety of European plum, P. domestica subsp. insititia , producing edible fruit, high in sugar, with a distinct, astringent taste and typically used in preserves and jams. It is self-fertile, meaning that it does not require another tree for pollination. However, planting two different cultivars is recommended to produce higher quality fruit.The cultivar 'Shropshire Prune' is the most popular variety of Damson plum in the United States. Damson plum trees tolerate many types of soil and prefer a site in full sun with medium moisture and good drainage. It is cold hardy, resistant to diseases, and needs little maintenance. The tree has a moderate growth rate of 13 to 24 inches a year, but the mature size of the tree depends on the version you choose, standard or dwarf. In addition to providing fruit, Damson plum trees can be grown as a tough hedge or windbreak. Diseases, Insect Pests, and Other Plant Problems: Prone to split-pit and susceptible to black knot. Aphids can be a common problem to all plum trees.
