Nigella sativa
Nigella sativa is the culinary fennel flower grown for aromatic black seeds known as black cumin. Plants are compact and fine textured and suit sunny herb beds and borders. White to pale blue flowers are followed by inflated seed pods that dry well. Grow as a warm season annual in full sun and well drained soil. A relatively long, warm season is needed for reliable seed ripening.
