Taiwanese vs. Vietnamese food

Actually, I was meaning to ask you (and/or @finley, or anyone else who knows) - do you know if it’s possible to get wild betel leaves here? I’m talking about Piper sarmentosum/Piper lolot, which I think is different from the betel leaves they wrap betel/areca nut in. It’s for making bo la lot.

The seeds would also maybe be fine, as long as they’re not too difficult to grow. Couldn’t find those online or from the big Taiwanese seed companies either.
