What Is Hollyhock?
The term “hollyhock” is generally used as a collective term for the genus Alcea, which consists of approximately 60 flowering varieties.1 This article will focus on Alcea rosea, which is the most common species of all the Alcea plants.2
Hollyhock was originally from China, where it was eaten as a potherb. It is typically abundant in Europe and Asia, but also thrives in the U.S. and other regions due to its hardy nature. One of the possible reasons this plant is called hollyhock is because the first plants sent to Southern Europe came from the Holy Land.
In earlier times, hollyhock was especially popular among the Spanish, who thought it to be the perfect reflection of God’s love because the plant was extremely enduring.3 Over the years, however, its popularity as a garden plant has waned due to its susceptibility to multiple diseases and pests, especially a fungus gardeners call “rust.”
Rust, or Puccinia malvacearum, usually grows on hollyhock leaves and can cause them to become severely disfigured. While hollyhock rust may cause you to have second thoughts about planting your own hollyhock herbs, there are ways to prevent it from infecting your beloved plants.4

• May relieve inflammation — Brazilians and Chileans use hollyhock leaves as a poultice to alleviate inflammation and tumors. Hollyhock seeds may also be crushed and applied topically to treat abscesses.7

• Natural cotton or fabric dye — Hollyhocks have been used to dye cotton for over 200 years. In fact, the oldest documentation of dyeing using hollyhock flowers dates back to the 19th century. Germans first started using hollyhock to add color to wine, but later began using it on fabric as well. Hollyhock flowers in lighter shades produce a yellow to a golden brown hue, while the darker variants produce shades that can be as light as lilac or as dark as deep mauve.8
