I assume you are referring to Echinacea if they are purple. I've never seen mature Echinacea seed heads contain fuzzy chaff or little brown seeds. Seeds should be a buff/ivory or beige color. Once you remove the outer spikes you are left with a head of seeds. I use tweezers to grab/pull them from the head. Can't imagine you already have mature seed heads so early in zone 5?
