Sanguinaria is a plant genus comprising just one species, namely Sanguinaria canadensis. This perennial flowering plant is native to the eastern parts of Canada and the United States. It is commonly known as bloodroot, most likely due to the red liquid derived from the root of this plant. It was used to make dyes. The narrow stalk grows 6 to 10 inches in height and features grayish-green basal leaves. Each plant sprouts just one white flower with a yellow center. It is an ideal ground cover for shade gardens or rock gardens.
There are several things to consider when planting and growing bloodroot. The condition of the soil, the climate, and certain pests or diseases can affect the health of Sanguinaria canadensis.
Climate
This plant thrives in hardiness zones 3 to 8. It should be planted in a location that is partially shaded or fully shaded from the sun.
Soil Conditions
Plant the bloodroot in humus-rich soil that is well-draining. Poorly draining soil may lead to root rot, which is a condition that deteriorates the structure and function of the plants root system. The soil should have a neutral pH, or close to it. It is a good idea to add mulch to protect it from the elements.
Watering and Fertilizers
The bloodroot does well in moist soil so water it regularly. Avoid over-watering this plant. Too much water may lead to root rot. This plant spreads quickly, so it doesn’t need additional fertilizers to grow.
Propagation
The best way to propagate this plant is by sowing seeds. Another option is to divide the rhizome, which is the underground stem, and transplant in another location.
Pests and Diseases
There aren’t any insects or microorganisms which are common to this plant species.
