Table 14.--Major retailers' proportionate purchases of celery, whole stalks versus hearts, by market area Market Area Whole Stalks Hearts Totals -------Percenta---- Philadelphia 82 18 100 Boston 58 42 100 Detroit 82 18 100 percentages are based on an overall, weighted average volume reported by all firms within cities. Small wholesalers in all three cities were found to purchase whole-stalk celery almost exclusively, but larger wholesalers and full-service wholesalers handled from one to 15 percent hearts. Celery hearts were found to constitute a substantial volume at the retail level, particularly in Boston. Accurate data were not available as to the proportion of hearts supplied by repackers in each of the market areas, but the quantity is quite large. Repackers were apparently using Florida whole-stalk celery to make hearts. Most hearts prepared by repackers were found to be about 10 inches long and packaged in a cardboard tray inside a poly bag or simply in poly bags. California hearts that were seen in the markets were substantially shorter, usually about 8 1/2 inches long. Several firms complained that Florida hearts did not hold up as well because of excessive leaves. They suggested that shortening them to the California length would alle- viate the problem.
