Used through the millennia for everything from bleeding to sore throat and fever, yarrow is an herbal medicine chest essential. Deeply feathered leaves gave rise to the Latin species name “millefolium,” meaning “thousand-leafed.” The white flowers are borne on upright stalks in flat-topped clusters. Yarrow is a spreading perennial with a robust will to live. It is completely drought tolerant and found in many wild locations. The pernicious rhizomes spread readily in fertile soil, so beware of planting in your veggie garden! Great plant for an herbal lawn since it doesn't seem to mind the weedeater!
