Asparagus

Overview

Asparagus has been grown in the United States since colonial times, but commercial production did not begin until the mid 1800s. Asparagus is a high-value, labor-intensive perennial vegetable crop. Essentially all of the U.S. commercial production occurs in California, Michigan and Washington, and it is harvested primarily in the January to June period. Complemented by off-season imports mainly from Mexico and Peru, fresh asparagus may be found year round in local markets.

About 74 percent of the asparagus produced in the United States was intended for freshmarket uses in 2004 (ERS 2005b). The remainder of the crop was frozen or canned. Most U.S. fresh market asparagus production is of the dark green form, with only minimal production of white (blanched) or light green asparagus, which are produced in the absence of sunlight. In addition to blanching, value-added for asparagus includes the processing of asparagus for pickling, which can bring growers a price premium and can be sold in winter months when prices are higher given lower supply (Ohio State University).  March 2006 . . .  Asparagus
