Hieracium murorum, the wall hawkweed, is a species of flowering plant in the sunflower family. It is native to Europe and naturalized in some of the colder regions of North America
Since hawkweed often grows in low-nutrient, low-organic soils, amending the area with fertilizer and organic matter can help reduce re-infestation by hawkweed when combined with active management of the hawkweed.
