Plant characteristics and classification of sorrel
Origin and occurrence of the sorrel
The common sorrel is native to Central and Western Europe. Due to its persistent way of life and partly invasive spreading it is to be found as neophyte also in many other countries and continents such as the USA, South Europe, and the Middle East.
Since sorrel is a perennial plant, it can be found on many nutrient-rich meadows, wild meadows and roadsides. Since the seeds can survive for a long time, the plant is able to colonize large areas within a short space of time.
Plant order of sorrel
Common sorrel – belongs to the knotweed family (Polygonaceae). The plant is related to important crops such as pieplant or buckwheat, but also to exotic herbs such as Vietnamese cilantro. The genus includes more than 120 species that are found almost all in the northern hemisphere. All plants contain oxalic acid. In addition to the well-known common sorrel (Rumex acetosa), the species curley dock (Rumex crispus) as well as the sheep’s sorrel (Rumex acetosella) are very common here.
Gradually also known is the blood dock (Rumex sanguineus), which, as a kitchen herb, is preferred especially because of its milder taste.
Look and characteristics of the sorrel
Sorrel is a perennial, hardy, and herbaceous plant that has high nutritional needs. The common sorrel can reach heights of growth up to one meter (40 in). On average, however, it is usually smaller and reaches heights around 25 to 50 cm (10 to 20 in). The plant has a brown to brown-black rhizome. The plant has a rhizome, which is directly connected to the stem axis and acts as a hibernating organ.
The smooth and elongated leaves are colored dark green to reddish depending on the content of oxalic acid. The more oxalic acid is contained, the more reddish they are. Striking is the eye-catching veining that sometimes resembles a herringbone pattern. In the young stage, sorrel grows as a rosette with rather elongated and thick leaves from the ground. Later, the pointed tapered leaves sit singly on the almost square stalk.
Heyday of the common sorrel is usually between mid-May to early September. The plant produces rather inconspicuous flowers, which usually look reddish to rust-colored. The flowers grow in a panicle, which is referred to here as pseudo whorl.
During fruit ripening, small black to brown nut fruits with small wings are formed. Each plant forms a rather high number of seeds.
Sorrel – cultivation and care
Sorrel is a relatively undemanding plant. It grows and thrives best in partially shaded to sunny spots.
The soil should be moist, nutritious and well humic. Inasmuch as sorrel is planted as a kitchen herb, it is advisable to choose a partially shaded location, as the plant and the leaves remain smaller.
The sowing of the seeds should take place between March (in the cold frame or balcony) and April (outdoors). It is also quite possible to cultivate the plants on the windowsill or in the indoor greenhouse, in order to replant them in the field or on the balcony around April. The plant needs sufficient heat with temperatures around 15 ° C / 59 ° F. The seeds are only superficially pressed on the ground, because sorrel needs light to germ.
For pre-cultivation a relatively low-nutrient soil is recommended. In contrast, the planting soil should not be too porous, like loamy and nutritious. In the field, the soil should therefore be pre-fertilized. It is advisable to use compost or a previous green manure. When potting soil is used, fertilization is not required as most commercially available soils are pre-fertilized.
Propagation may also take place by division of older plants. Since sorrel tends to spread uncontrollably, the plants should be kept in pots in their home garden. Especially the long roots (up to 150 cm / 5 ft) are responsible for the fact, that the plant grows on various new places in the garden. Other plants are sometimes affected and displaced. A fight by chopping the root is not possible, instead countless new roots are formed.
At the time of harvest, the leaves should be used fresh. Drying and freezing without water is not or only partially recommended as a preservative method. However, a preservation by pickle in oil is possible.
Sorrel and its use
Sorrel was already valued in antiquity. In ancient Greece, Egypt and the Romans, it was eaten as a nutrient against vitamin and mineral deficiencies, but was also used to reduce fever
Sorrel in the kitchen
Sorrel is becoming more and more fashionable. Especially in natural food shops there are more products to buy at the season. Alternatively, you can collect it yourself. The deadline of the last harvest day is the 24th of June. From this date, the concentration of oxalic acid, which gives the herb the bitter taste, increases and makes the herb unpleasant in the taste and irritates the stomach. Therefore, sorrel should be eaten afterwards only occasionally and in small quantities.
A feature that allows one to evaluate the oxalic acid content without tasting the plant is the coloring of the leaves. If the leaves are consistently green, the content is not as high as when the leaves start to turn red or are already completely red in color. Accordingly, only the green, young leaves should be collected.
The taste of sorrel can be described as sour and fresh, which is why it suits especially well in combination with lettuce. Alternatively, the herb can be prepared like spinach or can be found in recipes with herb butter, herb quark or the well-known sorrel soup. For the soup, the herb is usually pureed and refined with other herbs such as parsley or chervil. By the way, the herb is also part of the famous Frankfurt sauce.
Sorrel should always be used fresh. The aroma or taste is almost completely lost during drying. People who complain of kidney problems should eat only limited of it, since the contained oxalic acid may promote the formation of kidney stones.
Flower buds and young shoots are also suitable for cooking and as a spicy addition.
Sorrel is not suitable for drying. To use it in winter, it must be frozen in water or placed in oil. Iron-containing pots should be avoided when cooking with sorrel, otherwise it will easily take on a metallic taste.
The seeds can be dried and used in winter as germ seed or for tea preparation.
