The seeds of this European biennial of the Umbellifer family are well known for their use in confectionery, perfumery, and flavouring. The plant has a fleshy carrot-like root, and grows 1 to 2 ft. high, having finely-divided leaves and umbels of small white flowers. The seeds are sown in March and April in shallow drills a foot apart; the seedlings are thinned out about 8 in. apart in due course, and the soil is kept free from weeds by occasional hoeing. The seeds ripen in July and August following the year of sowing.
