Cultivation of watercress is practical on both a large-scale and a garden-scale. The new watercress is currently being trialled but early findings look promising, with a research paper1 that identifies the exact gene expression differences between ‘Boldrewood’ and the watercress currently available in the supermarkets. Watercress was one of the first green vegetables we have evidence of early humans eating. Common garden cress, or peppergrass… It is frequently produced around the headwaters of chalk streams. Watercress contains iodine and high levels of vitamin K so should be included in your diet although it must be cooked when found in the wild. Keep leaves above the surface of the water. Payne AC, Clarkson GJJ, Rothwell S and Taylor, G (2015). Watercress can also be grown in consistently wet soil with a soil pH of 6.5-7.5 in full sun, or you can mimic natural conditions by growing watercress plants in a bucket or other container. Voutsina N, Payne AC, Hancock RD, Clarkson GJJ, Rothwell S, Chapman MA, Taylor G (2016). Hi Brian Health experts say the benefits of eating watercress are many, and that one can eat watercress … At the same time, the group has gone back to old-fashioned plant breeding and selection and made new crosses between different watercress types to come up with a whole array of leaves that are now being investigated for their chemo-preventative (anti-cancer) properties. ; Brassicaceae) transcriptome using RNASeq and identification of candidate genes for important phytonutrient traits linked to human health. BMC Genomics (In Press). T. majus belongs to the family Tropaeolaceae, a sister taxon to the Brassicaceae within the order Brassicales. Also sold as sprouts, the edible shoots are harvested days after germination. Watercress is listed in some sources as belonging to the genus Rorippa, although molecular evidence shows those aquatic species with hollow stems are more closely related to Cardamine than Rorippa. [4] It holds a Watercress Festival that brings in more than 15,000 visitors every year and a preserved steam railway line has been named after the local crop. In recent years,[when?] His research identifies the genes that are important for adaptation, speciation and domestication; therefore it is important for the fields of evolutionary biology, genomics and mitigating climate change. I belong to a fly fishing club in the U.K. and this hot (2018) summer there has been so much watercress on our rivers that trout fishing in August through to October has been almost impossible to carry out. Last summer was quite a bloom due to the weather; I would expect it to continue growing in similar quantities though, more seeds in the right conditions = more plants. The stems are usually green but can be red to purple. Download a PDF of our prospectus or order a printed copy to be delivered to your door. Packages of watercress are stocked in some supermarkets and it may be available fresh, by the bunch, at farmers' markets and greengrocers. Watercress is a rapidly growing, perennial plant native to Europe and Asia. This meant that, in 1865 The Watercress Line (a railway line) was built to transport watercress from Alresford in Hampshire to London, allowing watercress farmers to sell their heavily in-demand crops at Covent Garden. A team of researchers from the University of Southampton will be attending The Watercress Festival in Alresford this weekend (Sunday 15 May) to talk about their latest work in developing new watercress varieties. [11], For the flower with the common name "nasturtium", see, "Effects of domestic processing methods on the phytochemical content of watercress (, "DPDx - Laboratory Identification of Parasitic Diseases of Public Health Concern: Fascioliasis",, Creative Commons Attribution-ShareAlike License, This page was last edited on 9 October 2020, at 09:24. In some regions, watercress is regarded as a weed, in other regions as an aquatic vegetable or herb. ‘Boldrewood’ has a promising future for those who prefer a tiny sweeter leaf. This gives watercress the peppery flavour with which we are all familiar. Watercress (Nasturtium officinale), perhaps the most popular of the edible cresses, is a hardy creeping perennial plant, native to Europe but extensively naturalized elsewhere in streams, pools, and ditches. Small green pods looking similar to pea pods. The town of Alresford, near Winchester, is considered to be the nation's watercress capital. 1. Sowing: Barely cover garden cress seeds. Small, white, and green flowers are produced in clusters and are frequently visited by insects, especially hoverflies, such as Eristalis flies.[2]. KOREAN WATERCRESS (minari) The taste is vegetal and very slightly bitter; it adds a great crunch and flavor. It is a valuable addition to any plate being the most nutrient dense of any vegetable – packed full of vitamins A and C, calcium and most importantly glucosinolate. Required fields are marked *. Hollow and usually floating although they can be erect or when lying along the ground can develop rootlets at the leaf nodes. Being semi-aquatic, watercress is well-suited to hydroponic cultivation, thriving best in water that is slightly alkaline. He works with a range of plants (and some animals) and carries out detailed genetic and genomic investigations comparing populations or species. NASTURTIUM (Tropaeolum majus) is grown both for its delicious gold to scarlet … Another research paper 2, with Dr Mark Chapman and PhD student Nikol … When collecting Watercress from the wild it must be cooked as out of site upstream there might be sheep and if so there is the potential for liver flukes, which can cause fascioliasis, a nasty liver disease. Please note that each and every hedgerow item you come across may vary in appearance to these photos. Professor Taylor says: “Watercress has been cultivated in the UK since 1808, with a particular focus in Hampshire and very little has changed – watercress prefers highly alkaline water and can be picked through much of the year. Br. If you have access to a slow moving brook, sow watercress seeds (or transplant store-bought) along the margin of the brook, using small stones to hold plants in place. What we are concerned about is if we leave these enormous tranches of watercress in place – will the seedpods germinate and will we get the same profusion of watercress in the same places every year now?
