Rumex - sorrel - is a genus of dicotyledonous herbaceous plants of the family Polygonaceae. Its leaves are up to 15 cm long and rounded, light green in color: they resemble those of spinach. The very recognizable fruit is an achene with three membranous wings; the fruits are grouped in clusters.
Water the seedlings regularly, and keep and eye on them if the weather is dry. In pot, water once or twice a week in warm weather, once every 2 weeks the rest of the year.A quick note when watering : sorrel is more bitter if it is grown in moist soil!
A very easily grown plant, it succeeds in most soils, preferring a moist moderately fertile well-drained soil in a sunny position[200]. Formerly cultivated for its edible leaves
Plants can contain quite high levels of oxalic acid, which is what gives the leaves of many members of this genus an acid-lemon flavour. Perfectly alright in small quantities, the leaves should not be eaten in large amounts since the oxalic acid can lock-up other nutrients in the food, especially calcium, thus causing mineral deficiencies. The oxalic acid content will be reduced if the plant is cooked. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition
