Common mallow (Malva neglecta)

The common burdock (Arctium minus) hails from Eurasia and is recognized as an invasive species in North America. It thrives in disturbed soils, forming extensive taproot systems that are difficult to eradicate. The seeds of common burdock can remain viable in the soil for many years. Once the seed coat is broken and exposed to moisture, germination can occur. Featuring large, heart-shaped leaves, it is sometimes confused with other broadleaf weeds, but its unique burrs distinguish it.
