I had never heard of a Hollyhock Mallow, but I came upon this delightful plant while visiting a friend last month. This interesting horticultural specimen was blooming in my friend’s neighbor’s yard. The profusion of pink blooms caught my attention from the corner of my eye, and I instantly raced over to get a closer look. Initially the flowers brought to mind common hollyhocks, but the form of this plant and the leaves were not quite the same as true hollyhocks. It took a little bit of internet sleuthing to arrive at the conclusion of what the plant was. I am still trying to learn more about this plant to determine if it is a good addition to the list of perennial plants for low water gardens.
Hollyhock Mallow, aka Malva alcea, is native to parts of Europe and Central Asia. As the common name implies, it is related to common hollyhocks (Alcea rosea) that many a grandmother has grown from seeds. Malva alcea is an herbaceous perennial that grows about 4′ in height, by 2-3′ wide. It has moderate water needs, but reportedly is drought tolerant. Unfortunately, it can fall prey to Japanese beetles, foliar nematodes, leafhoppers and spider mites. I wonder if it is plagued by the same leaf problems that make common hollyhocks look so beleaguered towards the end of the growing season. In some regions of the U.S. it has escaped cultivation and become naturalized. I do not know if it is invasive in Colorado. I look forward to learning more about this plant, and possibly testing it out in my own garden beds.
