This is a very interesting tree, grows fast when young. The bark has more vibrant colour bark when younger and the leaves give off a pleasant smell. The leaves turn from a lighter green to a nice dark green colour. I found these very hardy despite what some magazines say. I have had them outside in -12 as seedlings (2 yrs old ) and they bounce back very well. They will not grow as tall in our (subtropical!!) climate as in Hawaii etc. They can grow 25 metres+ but here are a little smaller! Only thing is as they grow quick it means I have to repot a little more often then I want to, but put in a bigger pot they make fantastic specimens when bigger as sold a few.
