I have it growing (although not realistic for a swap my way). They will grow very easily from cuttings. So if you know anyone with a plant just ask for a small cutting.

I have a piper nigrum growing like crazy. It's putting out a ton of runners. I had planned on rooting them to make some more new plants. I have one marked for a friend, but I could definitely root one for u if I'd like to trade.
I'd love a banana. What's your Thai banana like? I.e. could it be overwintered inside or in a greenhouse til next spring, it's edible, how big will it grow? Etc.
Let me know, I could totally have u a new plant ready in a couple weeks!
Happy growing!
