Malva verticillata

Malva verticillata, also known as the Chinese mallow or cluster mallow, is a species of the mallow genus Malva in the family of Malvaceae found in East Asia. M. verticillata is an annual or biennial that grow up to 1.7 meters in high and can inhabit woodland areas of different soil types. In temperate climates, it flowers from July to September and the seeds from August to October. The flowers of the plant are self-fertile but can also be pollinated by insects. The plant was an important leaf vegetable in pre-Han China and widely cultivated. Mallow is mentioned in Huangdi Neijing as one of the five consumable herbs (五菜) which included mallow (葵), pea leaves (藿), Allium macrostemon (薤), Welsh onion (蔥) and Garlic chives (韭). It was deemed to be a major vegetable until the Northern Wei, supposedly. The technology for domesticating mallow was well recorded in Qimin Yaoshu. The acreages were dwindled since the Tang dynasty. In his Nong Shu , Wang Zhen wrote that mallow came top among various vegetables, because 'it could be alternative in years of crop failure, or be marinated to serve with staples'. There were rare occasions that people cultivate or consume mallow, during the Ming dynasty.
