Oh, il have to have a look for that once my internet is installed, I've been using my mobile data and keep running out, it's supposed to be installed next week though so I'll look then
I like the sound of the gynostema, I like plants that climb or trail and being able to make it into a tea sounds good, does it have any health benefits?
I've tried yerba mate once before I think, I went to Argentina a couple of years ago and they sold souvenir cups with a metal straw with a filter on the end and a bag of it, I don't know if I did it wrong but it tasted like a mix between coffee, tobacco and an ash tray... So I didn't try it again :')
I'll have a read up on the plants you've said, I have east and West facing Windows and the balcony is facing the West
