I have overgrown guarana vines. A few years ago I had them properly climbing and the fruits came to maturity here in South Florida. I have photos in this forum I will retrieve.
https://tropicalfruitforum.com/index.php?topic=26237.msg305080#msg305080By overgrown this means they have been rooting in too. You come to dig up. If I get lots of interest in them I might dig up and pot some too, to send out via priority mail.
Price - Not sure yet. I will be listing this at Craigs List in a week
I see one guarana plant listing at ebay and one at Etsy...Craig's list for South Florida I see two maybes
