Sow in flats indoors or direct sow ¼“ deep spring through fall. Harvest leaves before flowering. Cilantro bolts easily; sow in succession for continuous harvest.
Collect seeds from seed heads that are fully dry. Shell by hand or by dancing, winnow to clean. Finish air-drying if necessary before sealing in airtight container. Cross-pollination may occur, isolate from other cilantro varieties by ½ mile.
