About
Prunus americana, commonly called the American plum, wild plum, or Marshall's large yellow sweet plum, is a species of Prunus native to North America.
Many cultivated varieties have been derived from the species. The fruit has a number of culinary uses and the domestic plum can be grafted to the rootstock. The fruit and roots were also used by Native Americans.
How to grow it
The white flowers are decorative in spring and its short, single leader makes it a popular residential landscape tree. According to botanist Charles Sprague Sargent,As an ornamental plant P. americana has real value; the long wand-like branches form a wide, graceful head which is handsome in winter and in spring is covered with masses of pure white flowers followed by ample bright foliage and abundant showy fruit.By 1950, over 200 forms had been selected for cultivation, with at least 50 cultivars known.
Where it grows
The species is native to North America from Saskatchewan and Idaho south to New Mexico and east to Québec, Maine and Florida. It has often been planted outside its native range and sometimes escapes cultivation.
Uses
The sour and sweet fruit is eaten fresh and is processed as preserves, jellies, jam and wine. The tree also forms an excellent rootstock upon which to graft the domestic plum. The Plains Indians and Cheyenne ate the plums; the latter used the branches for the Sun Dance. The Navajo used the roots to make a red dye.
