Echinacea, as I described earlier, was revolutionized by a cross that aimed at introducing a new flower color.

a flower opens, it is designed to be pollinated, either by insects and other animals, the wind, or itself, so you need to get in there just before it actually opens to stop that from happening to ensure that the seeds you end up harvesting have the daddy you want them to have. There are two parts to this: preventing self-pollination by emasculating, and preventing cross-pollination by covering the flower.
