Overview

Asparagus (Asparagus officinalis) 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 from January to June.

About 75 percent of the asparagus produced in the United States was intended for fresh-market uses in 2009 (NASS 2009). The remainder of the crop was canned or frozen. 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 is 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 1993).  September 2011 ...
