Aiton's Encyclopedia (1910)
a remarkable grass belonging to the same species as sorghum, kaffir corn, and durra. The stalk is succulent, but it lacks the sweetness of sorghum. The seeds are borne at the top of the stalk in panicles having long, straight branches. The tops or "brush" are used in broom-making, whence the name. Broom-corn is of two types, the dwarf and the standard. The dwarf grows from four to six feet high. The brush is used for whisk brooms and other small brooms. The standard type grows to twice the height of a man's head; the brush is from eighteen to thirty inches long, and is used for carpet brooms. Broom-corn is considered a native of the warmer parts of the Old World. The seed weighs fifty pounds to the bushel. About two quarts are required per acre. Broom-corn requires much the same growing conditions as corn, though it is able to withstand a greater degree of drought. The plant makes growth anywhere in the corn belt, but the harvest season requires dry weather as the brush is discolored by rain. The brush is cut off at maturity. The seeds are scraped off by hand, or are removed by a broom-corn thresher. The tops are sorted and are cured under cover to retain their bright, greenish color. After drying, the brush is put up in bales weighing from 300 to 400 pounds. The yield varies from a bale to two bales an acre. The price runs from $50 a ton to three times that sum. Broom-corn is a money crop in the region extending from central Illinois to the Panhandle of Texas. Illinois farmers ordinarily raise the standard brush; Oklahoma and Kansas, having a drier climate, produce the dwarf brush. The American crop for 1909 was the smallest for years, and prices ran as high as $200 per ton for choice lots. The yield was: Acres Total lbs.

The craft survives among Amish and artisan makers, and the flat, stitched broom the entry describes — an American invention credited to the Shakers — is still the shape of every broom sold.
