Nigella sativa (Black Cumin) Seeds

No, they are two species in the same genus. Love-in-a-mist (Nigella damascena) is the showier garden flower with a ruff of fine bracts, while Nigella sativa has smaller, paler flowers and is the one valued for its edible black seed, sold in shops as nigella seed or kalonji.

Pick the pods once they turn brown and papery but before they split open, then leave them in a paper bag somewhere warm and dry to finish ripening. Shake out the seeds, make sure they are completely dry and store them in an airtight jar.

Sow directly outdoors from late March to May, in a sunny spot. It dislikes being moved, so sow it where it is to grow, either in the ground or in a pot, and thin the seedlings rather than transplanting them.
