Production and cultivation
Palmaria palmata grows in the intertidal zone of cold coastal waters in the North Atlantic and Pacific, attaching to rocks and other algae via adhesion organs. It is found throughout Great Britain, Ireland, and Iceland, as well as in North America from Arctic Canada to New Jersey and from Alaska to California. It is also harvested in Japan and Korea.
The regular harvest season runs from September to April, with some regions beginning as early as June. To ensure sustainable harvesting, parts of the fronds are left intact after each harvest, allowing populations to recover and continue reproducing.
