    Distribution: According to Zohary (l.c.) “wild Alcea rosea L. seems to be indigenous almost exclusively on the Aegean islands and the adjacent Balkan Peninsula. The areas of its origin are no doubt the north-eastern Mediterranean countries, but not China which is beyond the natural range of the genus”. Elsewhere cultivated.

    In Pakistan it is extensively cultivated throughout.
