South Florida is just fine.
I just wouldn't want to trade plants from someone up north ... plants always seem to do better when they are within the same range (or as close as possible) ... or at least that's been my experience.
I also have some small katuk and cranberry hibiscus and they taste great! I can't wait until mine get huge so I can harvest as much as I want ... and start some cuttings.
I would love to trade some blackberries for your chaya cuttings. Yes, yes, let's do it! I hope they are easy to root ... I've been having a lot of trouble rooting tree collard cuttings. I'm usually good at that sort of thing but the collards just won't cooperate so I'm hoping the chaya is easier. I have a slight worry about the cyanide issue, but it seems like lots of folks eat it and are still alive ... you included. lol I am assuming it's like plants with oxalic acid ... as long as one don't eat them constantly it will alright on your system.
I've not done this before, but I'm assuming we just send each other purple mooseages to get our information for mailing?
Thanks so much for the offer,
