Answer:
The plant itself and pollinators are options when poinsettias (Euphorbia pulcherrima) want to be pollinated.
Specifically, each poinsettia has both female and male organs on the plant. The male organs tend to be made up of five (5) pollen-producing flowers. The female organ is made up of the female flower that contains the eggs. The pollen can be moved by plant body parts from the male to the female. Or the pollen can be moved by way of such pollinators as bugs (the Ello Sphinx moth, Erinnyes ello) and green bee members of the Halicitidae family.
