Height: 2-6 ft.

plant sale text: The genus name (Sanguisorba) refers to the juice of the plant reputed to stop bleeding. Burnet comes from an old French word for the color brown due to the European species which has reddish brown flowers. Our native Burnet has bottlebrush spikes of white flowers on stems that may reach 6 feet in height. Summer blooming and very tolerant of wet conditions, this plant will form a satisfying clump where happy. Good choice for a boggy area in your garden. The flowers can be quite dramatic.
