Wood sorrels profile

Wood sorrels, scientific name Oxalis corniculata like sunny, warm and humid environments. Wood sorrels are suitable to cover half shade in hot areas in summer. It has strong drought resistance and no cold resistance. The whole grass into medicine, has the effect of clearing heat and detoxifying, detumescence and disease.

Morphological characteristics of Wood sorrels

Stem: Herbs, stems erect or climbing.

Leaves: Leaflets are cord-shaped, 0.3 -- 1.5 x 0.5 -- 2cm, usually three L-leaflets circumferent, occasionally multi leaved. Pedicels ca. is 1 -- 7cm long, stipules very small but well defined.

Fruit: The fruit of Wood sorrels is a cone-shaped capsule, ca. 5-20 mm, bursting at maturity and ejecting seeds.

Seeds: Immature seeds of Wood sorrels are white, mature seeds are brown, seeds have rough protruding like fingerprints, and can easily adhere to the surface of objects.

Flowers: Single yellow, usually 5 petals, 0.7 -- 1cm long, pedicels 0.6 -- 1.5cm long.

Wood sorrels is a herb, 10-35 cm tall, pilose throughout. Rhizome is slightly hypertrophic. Stems are thin, much branched, erect or prostrate, rooting on stolon nodes.Leaves basal or alternate on stems;Stipules small, oblong or ovate, margin densely pubescent, base connexion with petiole, or lower stipules of the same plant obvious but upper stipules inconspicuous; Wood sorrels petiole is 1-13 cm long, base articulate; Wood sorrels has 3 leaflets, sessile, obcordate, 4-16 mm long and 4-22 mm wide, apex concave, base broadly cuneate, both surfaces pilose or glabrous, densely hairy along veins, margin appressed ciliate. Flowers are solitary or several clusters umbellate, axillary, pedicels pale red, nearly as long as the leaves; Wood sorrels pedicels are 4 -- 15 mm long, fruit extended after; Wood sorrels has 2 bracteoles, lanceolate, 2.5 -- 4 mm long, membranous; Wood sorrels has 5 sepals, lanceolate or oblong-lanceolate, 3-5 mm long, abaxially and margin pilose, persistent; Wood sorrels has 5 petals, yellow, oblong-obovate, 6 -- 8 mm long, 4 -- 5 mm wide; Wood sorrels has 10 stamens, filaments white translucent, sometimes sparsely pubescent, base connate, long and short interspersed, anthers larger and precociate for elders; Ovary is oblong, 5-loculed, puberulent, style 5, stigma capitate. Capsule is cylindrical, 1-2.5 cm long, 5 - rowed. Seeds are oblate, 1-1.5 mm long, brown or reddish brown, laterally ribbed reticulate. Flowering and fruiting period is from spring to autumn.

Ecological Habits of Wood Sorrels

Wood sorrels are found in grassy hillsides, along river valleys, along roadsides, near fields, on heath, or in damp places under forests.

Distribution area of Wood Sorrels

Wood sorrels are found throughout the country in grassy ponds on hillsides, along river valleys, along roadsides, near fields, on heath or in damp places under forests. It is found in temperate and subtropical Asia, Europe, Mediterranean and North America.

Wood sorrels widely distributed around the world, including Oceania, the Caribbean, Bermuda, China, Taiwan, Columbia, Australia, Canada, the cayman islands, Hawaii, costa rica, Guatemala, Indonesia, Japan, South Korea, the United States, Vietnam, Malaysia, Guam, Mexico, Mauritius, New Zealand, Papua New Guinea, Thailand, etc.

Growing methods of Wood sorrels

Safflower Wood sorrels are perennial herbaceous flowers. They are fond of sunny and humid climates and are not hardy to cold. In North China, they need to live indoors in winter. The soil requirements are not strict, but in loose, fertile and smooth drainage of sandy soil growth exuberant.

Safflower Wood sorrels are generally combined and repot in early April, and are bred by branching. The growing method is simple, the growth period often keeps the basin soil moist, pay attention to the appropriate water in summer, in order to increase the air humidity. Every half a month or so topdressing a thin cake fertilizer water, that can flower fanyemao.

In North China, the plants were moved indoors and placed in a sunny place in early and middle October. In winter control watering, pot soil is too wet, easy root rot, stop fertilization, room temperature is kept above 6℃ and can be safe over the winter.

Wood sorrels propagation methods

Wood sorrels propagate mainly from bulbs and branches, but also from seeds. The conjoined stems of Wood sorrels can be divided into mother corm, bud corm and leaf corm. Among the three kinds of corms, the mother corm has the ability of direct meristem, with the diameter of 2 ~ 2.5cm, and has residual leaf marks. In the leaf marks, there are latent buds, which can germinate and grow into corms successively. Bud corm is a small bulb growing on the mother corm, the diameter of the sphere is about 0.5 ~ 0.8cm. A leaf corm is a leafed corm that grows from a bud corm and produces leaves. Wood sorrels can blossom, about 1.2 ~ 1.5cm, and become a mother corm when it grows and develops. According to the experiment, the propagation coefficient of a single corm is high, and about 15 ~ 17 corms can be obtained on average for each single corm. The survival rate of female corm and leaf corn was similar in the open field, but the reproductive coefficient of leaf corn was the highest.
