Most of scholars prefer to mention only the primary grain, rice and the secondary grain, sweet potatoes when discussing food production and distribution in Taiwan during the Qing Dynasty while they ignore another important component of the grain market, the cultivation and price of “spring flowers” (wheat, barley, and beans). Local officials at the county level were required to report annual summer and autumn harvests. The autumn harvest meant rice and the summer harvest referred to the spring !owers and the early ripening rice. Both spring flowers and sweet potatoes were considered to be important secondary foods, however, according to government regulations, the summer harvest report included spring flowers but there was no mention of sweet potatoes. Sweet potatoes fed the poor and were cultivated on marginal land but spring !owers were grown on paddy land and rotated with the rice crop. Previous research has overlooked the important position of spring flowers. This article aims to provide a detailed account of the cultivation of spring flowers, and the association of its prices, chie!y wheat prices, with rice prices during the eighteenth century.
