Cultivation and uses

Several species are widely grown as garden flowers, while some are invasive weeds, particularly in the Americas where they are not native.

Many species are edible as leaf vegetables. Known as ebegümeci in Turkish, it is used as vegetable in Turkey in various forms such as stuffing the leaves with bulgur or rice or using the boiled leaves as side dish. Malva verticillata (Chinese: 冬寒菜; pinyin: dōngháncài, Korean: 동규자」is grown on a limited commercial scale in China; when made as a herbal infusion, it is used for its colon cleansing properties and as a weight loss supplement.

Very easily grown, short-lived perennials often grown as ornamental plants. Mild tasting young mallow leaves can be a substitute for lettuce, whereas older leaves are better cooked as a leafy green vegetable. The buds and flowers can be used in salads.

Cultivation is by sowing the seeds directly outdoors in early spring. The seed is easy to collect, and they will often spread themselves by seed.

In Catalonia (Southern Europe) they use the leaves to cure stinging nettles sting.
