Commercial farmers and home gardeners look forward to the seed catalogs received by mail every year the same way some people look forward to Victoria's Secret catalogs. If gardeners haven't changed seed sources in the last five to ten years, maybe it is time to see what's being offered these days.
Organic farmers look for heirloom seeds that have not been genetically altered. Like everything else, the price of seeds has gone up. It doesn't hurt to comparison shop and some catalogs offer a small discount.
