Oxalis, Oxalis, oxalis, "lucky clover" are annuals and perennials, some of which form tubers. The genus includes about 800 species of herbaceous perennials and shrubs, distributed throughout the globe. All oxalis are low plants, 8-10 cm high, densely covered with small trifoliate or pinnately compound leaves. The peculiarity of sorrel is its “exploding” fruits, which shoot out small seeds when ripe.

Etymology of the name OHALIS
The genus name reflects the sour taste of the plant (oxys translates as “spicy”). Common sorrel (Oxalis acetosella) is commonly known as hare cabbage or sorrel, in Germany this plant is known as “sour clover”.
Wild wood sorrel
Common sorrel, hare cabbage and sour clover, cuckoo clover / Oxalis acetosella
Common oxalis is a Eurasian species that grows very widely in nature: throughout Europe, the Caucasus, Turkey, China, Mongolia, and North America.
Common oxalis blooms in the forest in May.
Common sorrel is a perennial spring-flowering plant, only 5-10 cm high, with a thin creeping rhizome. The leaves are slightly pubescent above, trifoliate, on long petioles, the leaf petioles are reddish. The flowers are white, bisexual, regular and simple with a yellow spot in the center. Blooms in May.
Use of wood sorrel in cooking
The leaves contain oxalic acid. Common oxalis has a slight sour taste, BUT in large quantities it can cause irritation to the kidneys and urinary tract.
Leaves ground with sugar are used to prepare a vitamin drink.
Fresh leaves are used in salads, as a seasoning for egg dishes and soups.
Be careful: long-term use of this plant can lead to kidney disease!
The use of wood sorrel in ornamental gardening
Used in large parks and gardens to create a beautiful spring ground cover. Common oxalis reproduces well by seeds and by dividing the bush.

Types and varieties of oxalis suitable for growing in the garden
The genus includes more than 400 species, distributed in South America, Europe and Africa.
Carob sorrel, horned sorrel or yellow sorrel, northern sorrel / Oxalis corniculata, syn. Xanthoxalis corniculata
A perennial plant, it forms a thicket 20-25 cm high. The stems are thin, numerous, the leaves are trifoliate, petiolate.
Blooms in May-June with small yellow flowers. Most often, after planting, it begins to grow weeds throughout the entire area, drowning out other brothers in the flower garden.
Just like wood sorrel, it has a slightly sour taste and is edible in small quantities.
The garden form with brown-red leaves var. has the greatest decorative value. Purpurea. Can be used for planting in containers.
Oxalis adenophylla
Another winter-hardy species of sorrel. USDA Zone 4
A perennial plant, no more than 7 cm high, blooms in spring with pink flowers. The ferruginous sorrel has very beautiful leaves: they consist of many lobes (10-22), silvery. There are varieties with spots or veins.
Growing ferruginous oxalis
Ferruginous oxalis loves bright, but not direct sunlight. Does not like getting soaked, naturally grows in dry places. For the winter, it is advisable to mulch and hill up.
It can be grown at home, on window sills or balconies, but it still grows better in the garden. When growing indoors for the winter, it is advisable to put the pot in the refrigerator (basement, balcony) and water it carefully, along the edge of the pot. Also for the winter, like many container crops, you can dig it directly with the container in the garden and cover it with mulch or lutrasil on top.

Oxalis enneaphylla / Oxalis enneaphylla
A perennial plant 5-10 cm high, forming small clumps. It is beautiful, but in a culture in our region there may be problems when growing it. It blooms in May-June with white or pink flowers.
Oxalis nine-leaved
Growing nine-leaved wood sorrel
Planting requires acidic, humus-rich soil, good drainage and sun. For the winter, dry shelter is necessary.
Caring for oxalis in the garden
The main difficulty in caring for frost-resistant wood sorrel is to prevent them from growing uncontrollably. Ripe fruits of plants crack, throwing seeds over considerable distances, so you should not plant sorrel near vegetable beds.
Types and varieties of oxalis suitable for growing indoors
Oxalis triangularis, Oxalis regnellii Purple trefoil or False Trefoil / Oxalis triangularis, Oxalis regnellii
Oxalis triangularis is the trade name of the species, in the scientific literature it is more often found under the name Oxalis regnellii

A plant native to Central America. It grows well in a wide variety and grows well in a container. Suitable for growing indoors and in the garden, in container culture.
Volcanic oxalis bloom with small yellow flowers; their main advantage is their beautifully colored decorative leaves; the degree of decorativeness greatly depends on the lighting.
Features of growing volcanic sorrel
The dormant period of volcanic sorrel is weakly expressed. Loves coolness and diffused light. It is growing well. Watering is required moderately, without drying out. The soil is light, nutritious, with drainage. Good for pruning.
Interesting varieties of volcanic oxalis:
Molten Lava, Sunset Velvet, Burgundy, Plum Crazy, Molten Lava.
Volcanic wood sorrel variety Molten Lava (Molten Lava).
Caring for oxalis indoors
Oxalis are generally light-loving plants, but require shading during hot midday hours.
Oxalis grow well in cool rooms. In winter, during the dormant period, they are kept at a temperature of +12…+14 °C. Ortgis oxalis requires a temperature of +16…+18 °C in winter.
Deppe's oxalis loses its leaves in winter, and during this time the pot with the bulbs is placed in a cool place (+8...+10 °C). In spring, the bulbs are transplanted into fresh soil mixture. Water very rarely until leaves form.
For all other species, watering is plentiful, which is reduced to moderate in the fall.
Oxalis when grown indoors.
During the growing season, oxalis are fed weekly with a weak solution of complete mineral fertilizer. Replant in the spring every couple of years. For planting, use a soil mixture of peat, leaf soil, humus and sand (3:1:1:1).
Oxalis is rarely damaged by diseases and pests.
Height [edit]
Typically considered a weed of gardens, fields and lawns, it grows in full sun or shade. The alternate leaves of this plant are divided into three heart-shaped leaflets (a typical feature of other species of Oxalis)
, which can grow up to 2 cm wide.
These leaves curl at night (exhibiting nyctinasty) and open during the day for photosynthesis. Mature seed pods open explosively when disturbed (a trait very similar to the properties of mature seed pods or fruits of plants in the genus Impatiens
) and can disperse seeds up to 4 meters (about 13 ft). The flowers of the plant are hermaphroditic, blooming from July to October.
O. stricta
generally requires dry to moist, alkaline soils, preferring sandy and loamy soils for growth. It requires well-drained soil and can grow in low-nutrient soils. It does not tolerate shade well. [4]
Edible species of sorrel
Oxalis tuberosa / Oxalis tuberosa
Oxalis tubers contain a lot of starch - up to 25%. The color of the tubers is white, yellow, pink, bright red and purple.
The tuberous sorrel is not found in the wild. And it is impossible to propagate it by seeds - the flowers are sterile. It is bred exclusively using tubers.

Tubers of tuber oxalis.
Reproduction of wood oxalis
Propagated by daughter bulbs (Oxalis deppei), or by dividing the bush and cuttings. It all depends directly on the type of sorrel itself.
Plants are usually transplanted and divided after 2-4 years. The distance between plants in the garden is usually 20-30 cm when planting.
Some species grow weeds and it is quite difficult to stop their uncontrolled reproduction.
