The flowery look of poinsettias is from bracts, which are specialized leaves that are meant to make the plant look like large flowers in order to bring pollinators to the tiny flowers in the middle. Since they are actually leaves, you can pick and choose which leaves on this design will be pink, white or red, and which will be green.
