Cochlearia, or scurvy-grass, is a genus of about 30 low annual and perennial herbs in the cabbage family, mostly native to cool coastal, salt marsh and alpine areas of the northern hemisphere. Commonly grown members such as common scurvygrass (C. officinalis) suit cool, moist, sunny spots with good drainage.

About
Cochlearia (scurvy-grass or spoonwort) is a genus of about 30 species of annual and perennial herbs in the 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 salt enables them to avoid competition from larger, but less salt-tolerant plants; they also occur in alpine habitats in mountains and tundra.
They form low, rounded or creeping plants, typically 5–20 cm tall. The leaves are smoothly rounded, roughly spoon-shaped (the scientific name Cochlearia derives from the Latinized form, cocleare, of the Greek κοχλιάριον, kokhliárion, a spoon; this a diminutive of κόχλος, kókhlos, seashell), or in some species, lobed; typically 1–5 cm long, and with a fleshy texture. The flowers are white with four petals and are borne in short racemes.
