Did they come in any kind of packaging? Were you just given a brown bag of seeds? There is no mention of seeds on the USPS web site, however it probably coincides with their sunflower stamps and stationary. If they didn't come in any kind of professional packaging then there is probably no way to tell. If they are in some form of seed package try and research the producer.

sorry

Yes it came in some special packaging from the USPS. I thought it was a "out there" question, but I thought maybe there was someone that worked there or thought "hey! they do that EVERY YEAR! I have gotten them so many times, they are just LOVELY! They are xxxxxx kind of sunflower" xxxx=fill in the blank. lol

thanks anyway dear!
