Scurvy-grass (Cochlearia species; a.k.a. Scurvy grass, Scurvygrass) is a genus of about 25 species of annual and perennial herbs in the cabbage family Brassicaceae. They are widely distributed in temperate and arctic areas of the northern hemisphere, most commonly found in coastal regions, on cliff-tops and salt marshes where their high tolerance of saltProperties General Name Sodium chloride Chemical formula Na Cl Appearance White or clear solid CAS-number 7647-14-5 Physical Formula weight 58. 4 amu Melting point 1074 K (801 °C) Boiling point 1738 K (1465 °C) Density 2. 2 ×103 kg/ m3 Crystal structure f enables them to avoid competition from larger, but less salt-tolerant plants; they also occur in alpine habitats in mountainThis article is about the landform.

A mountain is generally much higher and stes and tundraIn physical geography, tundra is an area where tree growth is hindered by low temperatures and short growing seasons. The term tundra comes from the Finnish word tunturia which means treeless plain. There are three types of tundra: arctic tundra antarctic.

They form low, rounded or creeping plants, 5-20 cm tall. The leaves are smoothly rounded, roughly spoonA spoon is a common eating utensil, or item of cutlery, like a small spade, that occurs in a number of sizes and forms and is also suitable for liquid food and for stirring, and can have a number of other uses, including: courtship, combat and musical ent-shaped (the scientific name Cochlearia derives from Latin cochlea, a spoon), or in some species, lobed; typically 1-5 cm long, and with a fleshy texture. The flowerA flower is the reproductive organ of those plants classified as angiosperms ( flowering plants; Division Magnoliophyta). The function of a flower is to produce seeds through sexual reproduction''. For the higher plants, seeds are the next generation, ands are white, with four petals, and borne in short racemeA raceme is a type of inflorescence that is unbranched and indeterminate and bears pedicellate flowers (having short floral stalks called pedicels along the axis. In botany, axis means a shoot, in this case one bearing the flowers. In a raceme, the oldests.

Two species formerly included in the genus Cochlearia are now usually treated in separate genera:

HorseradishHorseradish Armoracia rusticana syn. Cochlearia armoracia is a root used as a condiment and to clear the sinuses in a hurry. It contains chemicals similar to mustard. It has at times been used as the bitter herbs in the Passover meal in some Jewish commun Armoracia rusticana (previously Cochlearia armoracia)
Wasabi Wasabia japonica (previously Cochlearia wasabi)

2 Uses

Scurvy-grass was extensively eaten in the past by sailors suffering from scurvy after returning from long voyages, as the leaves are rich in vitamin C, which cures this deficiency disease resulting from a lack of fresh vegetables in the diet. The leaves, which have a strongly peppery taste similar to the related Horseradish and Watercress, are also sometimes used in salads.

3 Scurvy-grass and roads

The advent of modern fast roads treated with salt in winter for ice clearance has resulted in the colonisation by scurvy-grass of many inland areas where it formerly did not occur. The scurvy-grass seeds become trapped on car wheels, transported often for a considerable distance, and then washed off, to grow in the salt-rich soil at the side of the road where other plants cannot survive. For the rapid colonisation of a British inland county between 1989- 2002, see Cochlearia danica in Worcestershire.
