Appearance and growth

Bloodroot is a variable species growing from 20 to 50 cm tall, normally with one large, sheath-like basal multi-lobed leaf

s are produced from March to May, with 8-12 delicate white petals and yellow reproductive parts. The flowers appear over clasping leaves while blooming. Plants are variable in leaf and flower shape and have in the past been separated out as different subspecies due to these variable shapes; currently most taxonomic treatments lump these different forms into one highly variable species. Bloodroot stores sap in an orange colored rhizome

, that grows shallowly under or at the soil surface. Over many years of growth, the branching rhizome can grow into a large colony. Plants start to bloom before the foliage unfolds in early spring and after blooming the leaves expand to their full size and go summer dormant in mid to late summer. Plants are found growing in moist to dry woods and thickets, often on flood plains and near shores or streams on slopes, they grow less frequently in clearings and meadows or on dunes, and are rarely found in disturbed sites. The flowers are pollinated by small bees and flies, seeds develop in elongated green pods 40 to 60 mm in length and ripen before the foliage goes dormant. The seeds are round in shape and when ripe are black to orange-red in color. Deer will feed on the plants in early spring.

Reproduction and genetics

Bloodroot is one of many plants whose seeds are spread by ants, a process called myrmecochory
Myrmecochory
Myrmecochory is seed dispersal by ants, an ecologically significant ant-plant interaction with worldwide distribution. Myrmecochorous plants produce seeds with elaiosomes, a term encompassing various external appendages or "food bodies" rich in lipids, amino acid, or other nutrients that are...

Elaiosome
Elaiosomes are fleshy structures that are attached to the seeds of many plant species. The elaiosome is rich in lipids and proteins, and may be variously shaped. Many plants have elaiosomes to attract ants, which take the seed to their nest and feed the elaiosome to their larvae...

 that attracts ants. The ants take the seeds to their nest, where they eat the elaiosomes, and put the seeds in their nest debris, where they are protected until they germinate. They also get the added bonus of growing in a medium made richer by the ant nest debris.

The double flowering
Double-flowered
"Double-flowered" describes varieties of flowers with extra petals, often containing flowers within flowers. The double-flowered trait is often noted alongside the scientific name with the abbreviation fl. pl....

 forms are prized by gardeners for their large showy white flowers, which are produced very early in the gardening season. Bloodroot flower petals are shed within a day or two of pollination so the flower display is short lived. The double forms bloom much longer than the normal forms, the double flowers are made up of stamens that have been changed into petal looking like parts, making pollination more difficult.

Plant geneticists have identified and sequenced genes which produce the enzymes required for this production. One enzyme involved is CYP80B1, which produces (S)-3'-hydroxy-N-methylcoclaurine and mendococlaurine from (S)-N-methylcoclaurine.

Bloodroot extracts are toxic to animal cells

Sanguinarine kills animal cells by blocking the action of Na+/K+-ATPase transmembrane proteins. As a result, applying bloodroot to the skin may destroy tissue and lead to the formation of a large scab, called an eschar
Eschar
An eschar is a slough or piece of dead tissue that is cast off from the surface of the skin, particularly after a burn injury, but also seen in gangrene, ulcer, fungal infections, necrotizing spider bite wounds, and exposure to cutaneous anthrax....

. Bloodroot and its extracts are thus considered escharotic.

In spite of supposed curative properties and historical use by Native Americans as an emetic, internal use is inadvisable. Although applying escharotic agents, including bloodroot, to the skin is sometimes suggested as a home treatment for skin cancer

, these attempts can be severely disfiguring. Salves derived from bloodroot cannot be relied on to remove an entire malignant tumor. Microscopic tumor deposits may remain after visible tumor tissue is burned away, and case reports have shown that in such instances tumor has recurred and/or metastasized.
