I have never had any problems growing Cherokee Purple and Craig sent me seeds for it from his source, J.D.Green, this history said something like 100 years old but that's shown to be a false claim.
If CP has you in a dither I highly suggest growing

Per the history when Donna Nelson sent me the seeds I sent some of the seeds she sent me, or maybe I grew it out and saved seeds to send to Craig, this happened back in 2004 I think,a long time to remember,ASAP to Craig,he grew it out and agreed that it was a variant of Cherokee Purple with just minor differences which Tania pointed out and Tania grew it herself as I recall. The info is all in the link above.
