Sharon, I don't know if the eucalyptus leaves would be good for smoke or not. There will be responses hopefully. Personally, when looking through the forest I would look for marijuana leaves, well, actually, look for bud!!! LOLL.
I still have seed for the Tea Tree that I was given by a fellow on Saltspring Island. I am really not too sure if I can grow these here, they are pretty tender. They grow on Saltspring Island,but they have a very warm micro climate over there.
I would really like to do some research on growing Tea Tree in my area. Will probably do it. I will also probably germinate some of the seeds and grow the tree inside my house until it is larger. I will treat it like I do all my other tropicals. I would love to get the honey from the Tea Tree, should I ever be able to protect it enough outside for it to mature. Have a wonderful day, beautiful day, good health wishes to all. Cindi
