Bloodroot In Flower

One of our earliest spring ephemerals, Bloodroot (Sanguinaria canadensis), a member of the Poppy family, greets the longer, warming days by having its short-lived flower emerge from within its protective leaf and spread its white petals wide open on sunny days. (The flower only opens on days when the temperature reaches 46 degrees, as that’s when pollinators are active.)

To encourage cross-pollination, when the flower opens it is in the female stage, relying on pollinators covered in pollen to land and drop pollen to the receptive stigma. Within a few hours of opening the stamens begin to release pollen. The flower will open for up to three days or until cross-pollination has occurred. Once pollination has taken place the flower begins to drop its petals.
