The Sicentific American 23, 19.2.1853
This plant was once cultivated to a great extent for the blue dye extracted from it, but has been greatly superseded by indigo. It might still be cultivated to great advantage, as it improves the color of indigo when mixed with it in a certain proportion. The plants, when just about flowering, are mown with a scythe, washed with water and sun dried; adter this they are ground into a paste, which, kept in heaps for about a fortnight, is then formed and pressed into solid balls. It is also occasionally sown as food for cattle, and has lately been recommended for this purpose under the name of pastel. Its vigorous growth and hardy nature are in its favor; but it will only flourish in very rich soils.
[The Woad Plant, we believe, is cultivated in some parts of the United States.]
