Chinese Mallow

Malva verticillata is native to East Asia, likely originating in China.

• Distributed across China, Korea, Japan, and parts of Southeast Asia
• Cultivated in China since ancient times as a vegetable crop
• Naturalized in parts of Europe, North America, and Australia
• Mentioned in classical Chinese agricultural texts dating back over 2,000 years
• Has been used in Traditional Chinese Medicine (TCM) for centuries
• The genus Malva has a long history of culinary and medicinal use in the Mediterranean and Europe, dating to ancient Greek and Roman times
• First described by Carl Linnaeus in 1759

An erect or ascending annual or biennial herb, 30 to 100 cm tall.

Stems:
• Erect, branched, green, with scattered stiff hairs
• Becoming somewhat woody at the base in biennial forms

Leaves:
• Orbicular to reniform (kidney-shaped), 3 to 10 cm in diameter
• Palmately veined, margins crenate to dentate (scalloped)
• Bright green, softly hairy on both surfaces
• Long petioles, 3 to 15 cm
• Arranged alternately along the stem

Flowers:
• Small, 1 to 1.5 cm in diameter
• Pink to pale purple or white petals, often with darker veins
• Born in dense whorls (verticillasters) in the upper leaf axils
• Epicalyx of 3 linear bracts

Fruit:
• Schizocarp that splits into 10 to 12 one-seeded segments (mericarps)
• Segments flattened, kidney-shaped, wrinkled, about 2 to 3 mm
• Green when immature, becoming brown and dry at maturity

Malva verticillata is an annual or biennial herb of temperate Eurasian ecosystems, commonly found in cultivated fields, garden margins, and disturbed ground where it serves as both a food source and a component of traditional meadow communities.

Habitat and Distribution:
• Native to East Asia, particularly China, Korea, and Japan
• Now naturalized across parts of Europe, North America, and Australia
• Found in cultivated fields, garden edges, roadsides, waste ground, and disturbed habitats
• Occurs at elevations from sea level to approximately 2,000 meters
• Prefers fertile, moist, well-drained soils in temperate climates
• Hardy to approximately -25\u00b0C as a seedling and -15\u00b0C as a mature plant

Growth and Life Cycle:
• Annual or biennial depending on climate and sowing time
• Germinates in spring or autumn; grows through the cool season
• Produces attractive whorls of flowers in the upper leaf axils during summer
• Self-seeds readily, maintaining populations in suitable habitats

Ecological Role:
• Flowers provide nectar and pollen for bees, hoverflies, and other beneficial insects
• Seeds are consumed by finches and other small songbirds
• The mucilaginous leaves and stems retain moisture, contributing to soil moisture conservation
• Serves as a host plant for several species of Lepidoptera (butterflies and moths)
• Deep taproot brings nutrients to the surface from subsoil layers

Pollination:
• Small pink to purple flowers are visited by a range of generalist pollinators
• Both self-pollination and insect-mediated cross-pollination occur'L, NULL, 'Chinese mallow leaves are a nutritious leafy vegetable.

• Per 100 g fresh leaves: approximately 30 to 40 kcal
• Good source of vitamins A (beta-carotene) and C
• Contains moderate amounts of calcium, iron, and phosphorus
• Provides dietary fiber from the mucilaginous polysaccharides
• Contains small amounts of B vitamins
• The mucilage has emollient and soothing properties valued in herbal medicine
• Low in fat and sodium

Propagated by seed directly sown in the field.

• Sow seeds in spring after last frost, or in early autumn in mild climates
• Scatter seeds thinly and cover lightly with 0.5 cm of fine soil
• Germination in 7 to 14 days at 15 to 20°C
• Thin seedlings to 15 to 20 cm apart
• Prefers fertile, moist, well-drained soils with pH 6.0 to 7.0
• Tolerates partial shade to full sun
• Keep soil consistently moist for tender leaf production
• Harvest leaves 40 to 60 days after sowing
• Cut-and-come-again harvesting encourages new growth
• Self-seeds readily if allowed to set seed

Culinary uses:
• Young leaves and tender shoots are boiled as a potherb in Chinese, Korean, and Japanese cuisine
• Used in soups, where the mucilage acts as a natural thickener
• In Korea, leaves are used in namul (seasoned vegetable side dishes)
• In China, mallow soup is a traditional dish with a silky, smooth texture
• Leaves can be added to congee (rice porridge) and stir-fries
• Dried leaves are reconstituted and used as a winter vegetable
• The mucilaginous quality makes it a natural thickening agent in stews
• Seeds are edible and can be used like those of other mallows
