Oxalis profile

Oxalis represents luck in many Western countries (such as The United Kingdom and the United States) because it is believed to be a plant only found in the Garden of Eden. In some countries, the plum flower in a poker card represents lucky Oxalis. The number of Oxalis represents true love, health, and fame. Oxalis is the national flower of Ireland.

Oxalis geographic distribution

Oxalis is native to Europe and North Africa and is cultivated throughout the world. Australia, New Zealand, The United Kingdom, Denmark and the Netherlands are the countries with the most forage grass varieties. Breeders in other countries, such as Sweden, Germany, the United States, France, Italy, Canada and Poland have also produced many famous varieties. 

Wild and cultivated species are found as far south as Mengla County in Yunnan province and Shangzhi County in Heilongjiang Province in the north. In China, there are about 10 wild species of Oxali and more than 200 species or cultivars that have been introduced and widely cultivated, and 162 cultivars of 14 species and cultivars have been introduced and cultivated in Yunnan province alone. 

Oxali Growth habit

Oxalis occurs mainly in warm temperate to tropical regions and is semi-spontaneous in moist grasslands, along river Banks, and along roadsides.Prefer humid warm climate, drought resistance, cold resistance. Oxalis is suitable for good drainage, rich in calcium cohesive soil growth. The growth cycle is generally 2-6 years, in warm conditions, often shortened to a biennial or annual. 

Oxalis is mostly cultivated as a lawn in parks and green Spaces.In the seedling stage, the growth is slow. After the seeds, Oxalis comes into the flat bed. Every morning and evening is for spraying, and always makes the flat bed surface moist until the emergence, which can reduce the number of water after emergence. But Oxalis still need to be careful, seedling management for about 30 to 50 days. In addition to paying attention to the water to keep the flat bed wet during, also remove weeds at any time, major is pulling, prevent the damage caused by weeds. 

Oxalis is highly invasive and does not require intertilled wedding, but nitrogen-fixing rhizobia can absorb nitrogen from the air and transform it into a form that plants can use. Therefore, phosphorus and potash fertilizer is the main fertilizer, no or little application of nitrogen. In the growth season and overwintering, supply sufficient water, in order to ensure exuberant growth and safety overwintering. Do a mowing before midsummer, and water enough to keep the plants green. Cut again before overwintering, water enough winter water. So, the next year when the green, flat surface no withered yellow leaves. 


Oxalis the main value


Oxalis is widely distributed, high adapted, good as livestock feed, but also good preceding crop, low surface coverage of the fine or orchard crops, as well as soil and water conservation, nectariferous, medicinal, green manure and lawn plants and fine ground crops. Since the 1970 s, the introduction of the Kunming region since the trials were successful, Oxalis has widespread application, produced good economic, social and ecological benefits, and appropriate artificial plants. 


Oxalis is sour and sweet, cool in taste, and has the functions of clearing away heat and dampness, detoxifying and reducing swelling. It is mainly used for colds, colitis, urinary tract infection, urinary calculi, neurasthenia and other diseases. It is also used externally for treating fall injuries, snakebite, carbuncles, furuncles, tinea pedis, eczema, burns and scalds. 


Oxalis increases soil organic matter and contributes to fertility. Due to the large growth rate of Oxalis, the biological yield is high, generally around 3,000 kilograms per mu. In summer, the soil was turned into soil after natural death or mowing, which played a significant role in improving the soil fertility of newly-built orchards and increasing the soil organic matter of old orchards.

Oxalis lowers soil temperatures in summer. When the ground temperature reaches 35℃, the absorption capacity of fruit tree roots decreases significantly. When Oxalis grows well, the ground temperature can be reduced by about 6-8℃ in summer, which is conducive to the normal growth of fruit tree roots.

Oxalis can stabilize the air humidity of orchard, facilitate the growth of fruit trees in summer, effectively promote the normal expansion of fruit, reduce the cracking and dropping of fruit, and realize the high quality and high yield of fruit trees.

Oxalis maintains a good soil structure.Due to the good covering effect of Oxalis, it can effectively avoid the flushing and deposition of rainwater on the soil and keep the soil structure in good condition.It is beneficial to the activity of soil microorganism and the metabolism of fruit tree root, the decomposition of various fertilizers and the degradation of harmful substances. 


Oxalis cultural implication


Every leaf in Oxalis has a different meaning.It contains all the things you want in life: fame, wealth, love and health. If you have them all, you are lucky.


Oxalis has come to symbolize many things over the years.According to legend, Oxalis is a sacred plant on St. Patrick's Day in Ireland, because its leaves form a triple, and "three" is a mysterious number in Celtic religion, like many others.St. Patrick used Oxalis to introduce the Christian doctrine of the Trinity in Ireland in the fifth century.
