Hollyhock is a plant species from family Malvaceae. Many varieties are used as ornamental plants. The flowering time ranges from February to October, depending on the location. It is also rarely cultivated as a medicinal and dyeing plant. Only black-red varieties are used for the extraction of dyes, as their petals contain anthocyanin malvidin in large quantities. In the past it was used to dye wine, liqueur, desserts, food and textiles, but today it is no longer of any significance. The plant can be used to dye violet-blue to grey. Because of the tannins and mucilages contained in ordinary hollyhock, it is found in numerous cough tea mixtures
