Not sure if you're still looking, but it was Matt Caudle. A while back there was a guy named Al Belk that was scamming people on Ebay. Don't remember what the scams were, but he was in North Carolina and got a lot of stuff from Leonard Jones' nursery when it closed. After people caught on to Belk and stopped buying from him, the same plants started being sold by a Matt Caudle, who was also in North Carolina. People thought it was either an alias for Belk or a friend of his and wouldn't buy any so Matt Caudle disappeared soon after.
As far as we've been able to find out, we think City Boy was a Leonard Jones plant that was never released before his nursery closed.
If you thought the auction was fun, come to the meeting!
