I somehow cant keep carnivores alive but I have quite a few trees that are becoming bonsai and are in various stages of training and some are getting there. Nothing older than 16 years though. I really love seeing them develop and how different that development can be. Two seeds from the same tree, planted at the same time can vary in growing behavior so much it is insane. Also most of them were dug up or the seeds were collected at special places to me, like from my dead grandmas garden/the garden I grew up in/vacations etc, so Im quite fond of them. Best hobby there is imo, but especially in the summer they need daily care and you will make mistakes as a beginner and kill some. Thats how it goes with plants.
I do have a few orchids as well. Mostly Bulbophyllum kept in a terrarium. Still getting the hang on them but giving tricky ones the right care and getting them to bloom is very rewarding.
