Nigella damascena (love-in-a-mist, ragged lady) is an annual garden flowering plant, belonging to the buttercup family Ranunculaceae. It is native to southern Europe (but adventive in more northern countries of Europe), north Africa and southwest Asia, where it is found on neglected, damp patches of land.
The specific epithet damascena relates to Damascus in Syria. The plant's common name comes from the flower being nestled in a ring of multifid, lacy bracts. It is also sometimes called devil-in-the-bush. It grows to 20–50 cm tall, with pinnately divided, thread-like, alternate leaves. The flowers, blooming in early summer, are blue, but can be white, pink, or pale purple. The fruit is a large and inflated capsule, growing from a compound ovary, and is composed of several united follicles, each containing numerous seeds. This is rather exceptional for a member of the buttercup family. The capsule becomes brown in late summer. The plant self-seeds, growing on the same spot year after year. It is now widely cultivated throughout the temperate world, and numerous cultivars have been developed for garden use.
