N. sativa grows to Template:Convert tall, with finely divided, linear (but not thread-like) leaves. The flowers are delicate, and usually colored pale blue and white, with five to ten petals.

The fruit is a large and inflated capsule composed of three to seven united follicles, each containing numerous seeds which are used as spice, sometimes as a replacement for black cumin (Bunium bulbocastanum).


The genus name Nigella is a diminutive of the Latin Template:Lang (black), referring to the seeds.<ref name=HyamPank95>Template:Cite book p. 341.</ref>

In English, N. sativa and its seed are variously called black caraway, black seed, black cumin, fennel flower, nigella, nutmeg flower, Roman coriander,<ref name=GRIN>Template:GRIN</ref> and kalonji (from Hindi-Urdu).<ref name=GB/>

Culinary uses

The seeds of N. sativa are used as a spice in Indian and Middle Eastern cuisines. The black seeds taste like a combination of onions, black pepper, and oregano. They have a pungent, bitter taste and smell.<ref name=GB>Template:Cite book</ref>

The dry-roasted seeds flavor curries, vegetables, and pulses. They can be used as a "pepper" in recipes with pod fruit, vegetables, salads, and poultry. In some cultures, the black seeds are used to flavor bread products, and are used as part of the spice mixture panch phoron (meaning a mixture of five spices) and alone in many recipes in Bengali cuisine and most recognizably in naan.<ref>Template:Cite web</ref> Nigella is also used in Armenian string cheese, a braided string cheese called majdouleh or majdouli in the Middle East.
