(Page down to Heading: "Style Persistence")
In Echinacea, each morning a row of anthers (male reproductive parts) emerges, bearing pollen. This row of anthers will become a row of styles by the next morning and a new row of anthers will open, moving upwards from the base of the head. Styles persist until they receive compatible pollen, after which they shrivel up. Thus style persistence is used as a measure of pollen limitation and can provide information about patterns of reproduction and pollen movement within populations of Echinacea.
There's a few photos at the site to illustrate this point.
Can see this process on some of my coneflower pics here.

So...I found out why the goldfinches are suddenly so active in the field:

Gophers and moles can be a problem eating the roots.
Goldfinches love the Echinacea seed crop and can clear out all the seed in a few days.
