Dill (Anethum graveolens) is an annual herb in the celery family Apiaceae. It is the only species in the genus Anethum. Dill is grown widely in Eurasia where its leaves and seeds are used as a herb or spice for flavouring food.
Dill grows up to 40–60 cm (16–24 in), with slender hollow stems and alternate, finely divided, softly delicate leaves 10–20 cm (4–8 in) long. The ultimate leaf divisions are 1–2 mm (0.04–0.08 in) broad, slightly broader than the similar leaves of fennel, which are threadlike, less than 1 mm (0.04 in) broad, but harder in texture. The flowers are white to yellow, in small umbels 2–9 cm (0.8–3.5 in) diameter.
