Ancient healing herb, used worldwide to stop bleeding, heal wounds, break fevers, and for headaches, colds, and flu. A handful of leaves in the bath soaks out aches and pains. Excellent butterfly and beneficial insect plant, with big flat clusters of small flowers—the shape butterflies prefer for landing and nectar-gathering. Forms a mat of roots and lacy leaves that hold soil and allow moisture to penetrate; good for sloped beds and edges of perennial plantings. It also makes a good low soil-holding understory for spring bulbs, before the yarrow sends up flowerstalks. 1000 seeds.
