Marvin Pritts, a professor of horticulture at Cornell University, asserts that less than 0.1% of Americans have likely ever eaten a blackcurrant. [3] Their rarity in the United States contrasts with the situation in Europe, which produces 99.1% of the world's blackcurrant crop, and where blackcurrant is a popular flavor of squash (cordial).

It is native to temperate parts of central and northern Europe and northern Asia, where it prefers damp fertile soils. It is widely cultivated both commercially and domestically.
Removal of Ribes used to be practiced in full force, which heavily affected blackcurrant production in the United States, however through a combination of the pathogen's hardiness and ability to travel airborne for nine hundred feet, as well as the Ribes ability to regrow from an extremely small root portion, researchers have focused their ...
Farming was the primary occupation of 72% of the national labor force in 1820, 60% in 1860, 37% in 1900, and 26% in 1920. The 50% level came in 1877. [8] [9] In 1900 29.1 million Americans were gainfully employed, of whom 10.4 million were on farms.
Early settlers discovered that the Great Plains were not the "Great American Desert," but they also found that the very harsh climate—with tornadoes, blizzards, drought, hail storms, floods, and grasshopper plagues [40] —made for a high risk of ruined crops. Many early settlers were financially ruined, especially in the early 1890s, and ...

The cotton industry in the United States hit a crisis in the early 1920s. Cotton and tobacco prices collapsed in 1920 following overproduction and the boll weevil pest wiped out the sea island cotton crop in 1921. Annual production slumped from 1,365,000 bales in the 1910s to 801,000 in the 1920s. [23]
