Have you ever did business with Pepper Joe?

I have not, but I found it while searching pepper seed.
I purchased seed from him once...lots of crossed seed. Bad idea. Try Refining Fire Chiles...click
here. An AMAZING selection, and he goes to a great deal of effort to make sure his peppers don't cross-pollinate...pricey, but worth it. Good people. (Read reviews at Dave's Garden...you can save yourself a LOT of grief.)
