So...I went out and snipped them off and will allow them to dry. I think in this weather they don't need to be in the dehydrator! This is pretty much all of the flowers here, so it's not a lot. Still, it's enough to try out and see if I want to grow more German Chamomile next year. It's a self-seeding annual but I don't think I left enough to self-seed!
The info says it has to be German chamomile, that the common roadside chamomile is virtually scent-free, and the Roman chamomile (which is a perennial) isn't the right kind for tea either.
Wikipedia provided this photo and the idea to mix the dry chamomile blossoms with cinnamon and dried apple bits. Might have to try that!
