Lepidium sativum L. - syn. Nasturtium sativum Medik., Thlaspi sativum Crantz. - Brassicaceae - garden cress, pepperwort, pepper grass, Gartenkresse

Annual herb, up to 60cm tall, native to western Asia and Northeast Africa, naturalized elsewhere, widely cultivated for sprouts; lower leaves pinnatisect or lyrate-pinnate, upper leaves linear, sessile; flowers small, 2-3mm, white to pinkish; seeds 3mm long, 1mm broad, brown.

„Garden cress is added to soups, sandwiches and salads for its tangy flavor. It is also eaten as sprouts, and the fresh or dried seed pods can be used as a peppery seasoning (haloon). In England, cut cress shoots are commonly used in sandwiches with boiled eggs, mayonnaise and salt.“ https://en.wikipedia.org/wiki/Garden_cress

Cress seedlings contain high levels (1.2mg/g fresh weight) of benzylglucosinolate (glucotropaeolin) and trace amounts of 2-phenethylglucosinolate in the first week following germination.
„Benzylglucosinolate degradation products were analysed in extracts of the seedlings of Lepidium sativum (‘curled cress’ and ‘plain cress’). Benzyl thiocyanate was positively identified in extracts of both types of cress, but it could not be detected after the onset of development of the true leaves. The relative percentages of benzylglucosinolate degradation products varied appreciably with age of the seedlings and with the length of time the shredded plant material was allowed to autolyse.“
