The species grow to 20–90 cm (8–35 in) tall, with finely divided leaves; the leaf segments are narrowly linear to threadlike. The flowers are white, yellow, pink, pale blue or pale purple, with five to ten petals. The fruit is a capsule composed of several united follicles, each containing numerous seeds; in some species (e.g. Nigella damascena), the capsule is large and inflated.
The seeds of Nigella sativa, known as kalonji, black cumin, black caraway, black coriander, roman coriander, black onion seed, onion seed, charnushka, git (in historical Roman cuisine),[2] or just nigella, are used as a spice and a condiment in South Asian, Ethiopian, Middle Eastern and Polish cuisines.[3]
Several species are grown as ornamental plants in gardens. Nigella damascena has been grown in English cottage gardens since the Elizabethan era, commonly called love-in-a-mist. Nigella hispanica is a taller species with larger blue flowers, red stamens, and grey leaves. Nigella seeds are self-sowing if the seed pods are left to mature.
The dried seed capsules can also be used in flower arrangements.

Dried pods are sniffed to restore a lost sense of smell. It is also used to repel some insects, much like mothballs.

Thymoquinone is a phytochemical compound found in the plant Nigella sativa. Dithymoquinone, kaempferol, Nigelladine B, Nigelladine, and Nigelladine sulphate also showed high docking scores.[19]
