Musk mallow (Malva moschata) was transported to North America by European settlers. Unfortunately, it has become invasive throughout much of the northwestern and northeastern parts of the United States, where it is likely to pop up in roadsides, along railroads and dry, grassy fields. Musk mallow often marks the location of old homesteads. Musk mallow is a hardy plant, suitable for growing in USDA plant hardiness zones 3 through 8. As with common mallow plants, it’s a good idea to consider the invasive potential before you consider growing musk mallow. Your local cooperative extension office is a good source of information. You can also contact the fish and wildlife service in your area.
