Hmm, that may be a more important and pressing mystery! LOL!
I used to live close enough to visit Baker's Acres at least once per spring and was totally spoiled about "having to choose" between countless Coleus. I thought their Coleus came from FL. The source would probably be in the south part of FL anyway. They used to send the funniest catalog just before they opened for the season. If you want to order Coleus online, I think they ship plants, and can attest that they're real and have amazing plants. I'm not letting myself cross that line. I get in enough trouble visiting the few stores I can find occasionally.
