Bunium flexuosum StokesConopodium denudatum Koch Conopodium majus is a perennial herbaceous flowering plant in the celery family, Apiaceae.

)[1] It has a smooth, slender, stem, up to 40 centimetres (16 in) high, much-divided leaves, and small, white flowers in many-rayed terminal compound umbels.

[2][3] The rounded "nut" (inconsistently described by authorities as a tuber,[2] corm, or root) is similar to a chestnut in its brown colour and its size, up to 25 millimetres (1 in) in diameter; its sweet, aromatic flavour has been compared to that of the chestnut, hazelnut, sweet potato, and Brazil nut.

[citation needed] The plant is common and native to western Europe, the British Isles and Norway.

[7] Palatable and nutritious, its eating qualities are widely praised, and it is popular among wild food foragers, but it remains a minor crop, due in part to its low yields and difficulty of harvest.
