Nigella–commonly called love-in-a-mist–is a ferny-leaved annual that produces light blue flowers surrounded by delicate, finely-divided leaflike bracts. Each flower becomes a balloon-like green seedpod that is striped with purple or bronze.
Nigella is a member of the buttercup family. Flowers appear in warm weather. In mild-winter regions, Nigella blooms in late winter and spring. The flowers and seedpods are often used in flower arrangements.
The Nigella genus consists of 20 species of stiffly erect, bushy annuals. Nigella is native to rocky slopes and fallow fields in the Mediterranean, Eurasia, and North Africa.
