Strong erect biennial or short-lived perennial herb, mostly unbranched, up to 3m tall, only known in cultivation (Asia, Europe); stem densely hirsute; leaves cordate to orbicular, 5-7 lobed or wavy-angled, 10-30 cm wide, rough, rugose, long-stalked, , crenate; flowers 7cm or more across, nearly sessile, in a long wand-like raceme or spike, many forms and colors (purple, deep purple, black, yellow or white).

„The investigations showed mucilage from flowers of Alcea to be superior to mucilages from leaves or flowers from Malva. High molecular weight acidic polysaccharides (HMWAPs) were isolated from the mucilages of leaves and flowers of both species. The molecular weight of all HMWAPs was in a range of 1.3 to 1.6 x 10(6) D. HMWAP-content in mucilage from flowers of Alcea was highest compared to content in mucilages from leaves or flowers from Malva. HMWAPs were found to be composed mainly of glucuronic acid, galacturonic acid, rhamnose and galactose.“
