Nile and Mediterranean regions, Sinai.
Europe, Mediterranean region, Asia; naturalized in some other temperate regions.
It resembles Malva ambigua Guss. and Malva mauritiana L. From Malva ambigua Guss. it differs in its glabrous fruits and from Malva mauritiana L. it can be differentiated on the basis of emarginate and smaller petals and fewer flowers in fascicles.
Malva sylvestris is a species of the mallow genus Malva in the family of Malvaceae and is considered to be the type species for the genus. Known as common mallow to English-speaking Europeans,[3] it acquired the common names of cheeses, high mallow and tall mallow (mauve des bois by the French)[4] as it migrated from its native home in Western Europe, North Africa and Asia through the English-speaking world.[5]
M. sylvestris is a vigorous plant with showy flowers of bright mauve-purple, with dark veins, standing 3–4 feet (0.91–1.22 m) high and growing freely in meadows, hedgerows and in fallow fields.[6]
It is one of several species of different genera sometimes referred to as Creeping Charlie, a term more commonly applied to Glechoma hederacea (ground ivy).[7]
One of the major areas which Malva Sylvestris grow is north east and central of Iran . Also in North Africa,[8] biennial[5][9] in the Mediterranean[8] and a perennial elsewhere.[8][10] It can be straight or decumbent,[3][10] branched, and covered with fine soft hairs or none at all,[9] M. sylvestris is pleasing in appearance when it first starts to flower, but as the summer advances, "the leaves lose their deep green color and the stems assume a ragged appearance".[6]
The leaves are borne upon the stem, are roundish, with numerous lobes, each 2–4 centimetres (0.79–1.57 in) long, 2–5 centimetres (0.79–1.97 in) broad and 5–10 centimetres (2.0–3.9 in) in diameter.[10] The leaves have hairs radiating from a common center, with prominent veins on the underside.[6]
Described as reddish-purple,[9] bright pinkish-purple with dark stripes[3] and bright mauve-purple,[6] the flowers of Malva sylvestris appear in axillary clusters[10] of 2 to 4[5] and form irregularly and elongated along the main stem with the flowers at the base opening first.[10]
M. sylvestris has an epicalyx (or false calyx) with oblong segments, two-thirds as long as calyx[10] or 2–3 millimeters long and 1.5 millimeters wide.[5] Its calyx is free to the middle, 3–6 millimeters long,[5] with broadly triangular lobes[5] or ovate mostly 5–7 millimeters long.[10] The flowers are 2–4 times as long as the calyx;[9]
Nutlets strongly reticulate (10–12 mericarps, usually without hair, with sharp angle between dorsal and lateral surfaces, 5–6 mm in diameter.[3][5]
Also called 'cheeses,'[6] seeds are brown to brownish green when ripe, about 2.5 millimeters long and wide[5][10] 5 to 7 millimeters in diameter[10] and are shaped like a cheese wheel.
Malva sylvestris spreads itself on waste and rough ground, by roads and railways throughout lowland England, Wales and Channel Islands, Siberia and scattered elsewhere.[3][9] It has been introduced to and has become naturalised in eastern Australia,[10] in the United States, Canada, and Mexico as an invasive species.[9]

Mauve, n. F., mallow, L. malva. So named from the similarity of the color to that of the petals of common mallow, {Malva sylvestris}.
In 1931, Maud Grieve wrote that the "use of this species of Mallow has been much superseded by marsh-mallow (Althaea officinalis), which possesses its properties in a superior degree, but it is still a favorite remedy with country people where marsh-mallow is not obtainable."[6] The flowers were spread on doorways and woven into garlands or chaplets for celebrating May Day.[6] The boiled young leaves are a vegetable eaten in several parts of Europe in the 19th century.[11]
In Morocco, Tunisia and Palestine, Malva leaves are steamed with garlic and tomatoes, and eaten as an appetizer or salad. In Egypt, the leaves are made into a stew-like vegetable dish, especially in winter, known as khobeiza, which is similar to Molokheia.
In traditional medicine, M. sylvestris has been used in herbalism. Mucilage is present in many of the family Malvaceae including M. sylvestris,[12][13] especially the fruit.[14] The seeds are used internally in a decoction or herbal tea as a demulcent,[11] and the leaves may be used in poultices as an emollient for external applications.[14]
The species has long been used as a natural yellow dye,[15] but dyes of various yellow-green colors can be obtained from the plant and its seeds.[16] A tincture of the flowers can make a sensitive test for alkalis.[6]
Plants previously often described as Malva sylvestris var. malaca are now considered a cultivar group Malva sylvestris Mauritiana Group.[8]
It is often grown as an ornamental plant for its attractive flowers, produced for a long period through the summer. Numerous cultivars have been selected and named.
Cultivars of Malva sylvestris include: 'Annita', 'Aurora', 'Bardsey Blue', 'Blue Fountain', 'Brave Heart', 'Cottenham Blue', 'Gibbortello', 'Harry Hay', 'Highnam', 'Inky Stripe', 'Knockout', 'Magic Hollyhock', 'Mest', 'Mystic Merlin', 'Perry's Blue', 'Purple Satin', 'Richard Perry', 'Tournai', 'Windsor Castle', 'Zebrina' (soft lavender-purple striped with deep maroon veins) [17] and 'Zebrina Zebra Magis'.
Malva vein clearing potyvirus which is transmitted by mechanical inoculation in a non-persistent manner via insects, such as Aphis umbrella (syn. Aphis malvae Koch) and Myzus persicae (all are Aphididae). The virus can be found in Tasmania, Brazil, the former Czechoslovakia, Germany, Israel, Italy, Portugal, California, Russia and the former Yugoslavia.[18][19]
M. sylvestris contains malvin and malonylmalvin.[20] It also contains the naphthoquinone malvone A, which is also a phytoalexin.[21]
