Range Description

B. verna is native to parts of central, southwest and southeast Europe (Marhold 2011). This species has been widely introduced to the rest of Europe where it has become naturalized (Rich 1991). The species is widespread in France, occurring in the majority of departments across the country with the exception of Lot-et-Garonne, Lot and Haute-Garonne to the south and 16 departments in the north (Association Tela Botanica 2000–2010). Further research is needed to gather information about the precise distribution of this species throughout the rest of its range.

Justification

European regional assessment: Data Deficient (DD)
EU 27 regional assessment: Data Deficient (DD)

Barbarea verna is assessed as Data Deficient as there is currently insufficient information available to evaluate this species. Information about its precise distribution, habitat preferences, population size and trend is needed, as well as its in situ conservation status and potential threats.

The genus Barbarea is listed in Annex I of the International Treaty on Plant Genetic Resources for Food and Agriculture as part of the brassica complex.

EURISCO reports seven germplasm accessions of B. verna held in European genebanks, four of which are reported to be of wild or weedy origin. Of the wild accessions, two originate from within Europe—one from Austria and the other from Spain (EURISCO Catalogue 2010). Further germplasm collection and duplicated ex situ storage is a priority for this species.

Barbarea verna

"Land cress" redirects here. For the winter annual plant, see Cardamine hirsuta.

Land cress (Barbarea verna), also known as American cress, bank cress, black wood cress, Belle Isle cress, Bermuda cress, early yellowrocket, early wintercress, scurvy cress, creasy greens, and upland cress, is a biennial herb in the family Brassicaceae. It is native to southwestern Europe, but is also cultivated in Florida. As it requires less water than watercress, it is easier to cultivate. Land cress has been cultivated as a leaf vegetable in England since the 17th century.

Land cress is considered a satisfactory substitute for watercress. It can be used in sandwiches, or salads, or cooked like spinach, or used in soup and fish.

Land cress can be grown easily in any garden. Like watercress, it loves water, but does not do well when partially submerged for long periods of time. This perennial needs full sun and frequent watering in any garden, unless near a direct source of water.

Synonyms include Barbarea praecox and Lepidum nativum. Other common names include dryland cress, cassabully, and American watercress. A variegated form is available.
