Wikipedia Abstract

Alcea rosea (common hollyhock; syn. Althaea chinensis Wall., Althaea ficifolia Cav., Althaea rosea Cav.) is an ornamental plant in the Malvaceae family. It was imported into western Europe from southwestern Asia and the Balkans during, or possibly before, the 15th century. William Turner, a herbalist of the time, gave it the name "holyoke" from which the English name derives.

Usage [2]  A fibre obtained from the stems is used in papermaking; The fibres are about 1.9mm long.

The fibres are cooked with lye for 2 hours and then ball milled for 3 hours or pounded with mallets. The paper is light tan in colour; The flowers are an alternative ingredient of 'Quick Return' herbal compost activator; This is a dried and powdered mixture of several herbs that can be added to a compost heap in order to speed up bacterial activity and thus shorten the time needed to make the compost; The seed contains 12% of a drying oil; The red anthocyanin constituent of the flowers is used as a litmus; A brown dye is obtained from the petals;
