It’s easy to take seeds for granted. Tiny dry pods hidden in packets and sacks, they make a brief appearance as gardeners and farmers collect them for future planting then later drop them into soil. They are not “what’s for dinner,” yet without them there would be no dinner. Seeds are the forgotten heroes of food—and of life itself.

Sharing these wellsprings of sustenance may sound innocuous enough, yet this increasingly popular exchange—and wider seed access—is up against a host of legal and economic obstacles. The players in this surreal saga, wherein the mere sharing of seeds is under attack, range from agriculture officials interpreting seed laws, to powerful corporations expanding their proprietary and market control.

Seed libraries—a type of agricultural commons where gardeners and farmers can borrow and share seed varieties, enriching their biodiversity and nutrition—have sprouted up across the U.S. in recent years, as more Americans seek connection to food and the land.
