Francis,
Try the Honey Rock Herb Farm, 113 Honey Rock Way, Louisville, TN at 984-0954. They've been in business for 13 or 14 years and are wonderful people! Don't know if you are new to the forum, but I'm a lurker (don't post too often), but the Honey Rock people are too good not to talk about.

Honey Rock is good. So is Erin's Meadow Herb Farm. They're out by Oak Ridge. Their website is below.
Also check out Blooms Days at the UT Gardens June 24-25. There should be several herb vendors there. I bought some nice sage from Honey Rock there last year.

Just a small correction -- BloomsDays are actually June 25-26. :-)
