Pollination of the Bloodroot
Bloodroot's flowers pollinate in a tricky way. Their blossoms do not contain any nectar, but the colorful petals and anthers attract insects, which manage to transfer pollen that they previously picked up while in their hopeless search for sugar. However, flowers bloom in areas long before bees are around to be tricked. Observations on this indicate that the plants self pollinate readily. The cooler the climate, the less likely bloodroot is to be visited by bees (Sanders, 101).
Once bees are finished with the bloodroot, ants can take over. Some species of ants plant and harvest bloodroot seeds in a symbiotic relationship called "myrmecochory." Ants are attracted to the seeds by tiny proturbences, which contain oils and sweets. Ants will carry the seeds to their nests, where they eat part of it but discard the seed proper, and the seed will begin to grow (Sanders, 101).
