Hi Thr33crt,
My favourite plant to grow has to be Salvia divinorum. It seems to love it here and is growing very well for me. I also find it's rather satisfying taking cuttings. I have the 'Wasson And Hofmann' cultivar/ strain of it. I'd love to be able to add the 'Blosser', 'Luna', 'Paradox' and 'Appaloosa' cultivars/ strains of it to my collection one day. It seems rather difficult to find them though.
I rather like all the different cacti I'm growing as well.
I've recently got some grafting stock so I can have a go at that, as so far I've just grown them all on their own roots. I've put in another bunch of Lophophora Williamsii seeds so I can experiment with them first. (I've seen a lot of good info on cacti from you Wakinyan, so thanks for that!)
What plants are you hoping to start growing, Thr33crt
