Bloodroot is one of many plants whose seeds are spread by ants, a process called myrmecochory. The seeds have a fleshy organ called an elaiosome 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 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.
Bloodroot produces morphine-like benzylisoquinoline alkaloids, primarily the toxin sanguinarine. The alkaloids are transported to and stored in the rhizome. Comparing the biosynthesis of morphine and sanguinarine, the final intermediate in common is (S)-reticuline. A number of plants in Papaveraceae and Ranunculaceae, as well as plants in the genus Colchicum (family Colchicaceae) and genus Chondodendron (family Menispermaceae), also produce such benzylisoquinoline alkaloids.
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 from (S)-N-methylcoclaurine.
