The plant produces one-inch pods that, when dry, split open to reveal bright red seeds, or peas, that have a black spot on one end.

The scientific name for the plant is Abrus precatorius. Other common names for the rosary pea include Buddhist rosary bead, precatory bean, Indian bead, lucky bean or love bean.
