Sanguinaria canadensis

A fast growing, rhizomatous spreading perennial native to rich deciduous woodlands of eastern North America ( from southern Manitoba to the north shore of Lake Superior to Chapleau, Ontario to Haileybury, Ontario to Gaspe and Cape Breton, Nova Scotia; south to eastern Texas to northern Florida ). In the Windsor/Essex County, Ontario region; it was abundant around Point Pelee, the Lake Erie islands as well as the Ohio shore during the 1800s. It can reach up to 1 or very rarely 2 feet in height and 20 inches in width.
The gray-green leaves are deeply lobed and scalloped, up to 8 x 12 inches; they die back to the ground in October ( earlier if summer drought occurs - will reappear following year ).
The anemone-like flowers are pure white, up to 1.5 inches across and are borne in early spring.
The sap is bright red.
Hardy zones 2 to 7 in a cool partial to fully shady sites on moist, light, humus-rich, well drained soil. It enjoys a mulch of shredded leaves applied during late autumn. Propagation is from division of rhizomes as the plant begins to go dormant after blooming. Seed can be sown immediately upon ripening but may take as much as 1 1/2 years to germinate.
