This is not a very clear picture. I apologize for that. I couldn't find a better one. If I do, I'll post it later. I've looked at pics of both German and Roman and I still can't tell. This was just labelled chamomile when I bought it. It grew about a foot high.

Also, does anybody know if it sets seed? The heads are very hard when they dry. Like little rocks. If there are seeds in there, I can't tell.
