Well, I hope annual trimming will slow the trees growth a bit. I'll all up for filling in the pool but my wife would bury me in it if I did that. The bees... actually I think they're bumble bees not carpenter bees. They don't bother me much. It's the snails I'm stepping on that are really irritating!

Jatropha?

Northboy 12 ,yes, This turned out to be very mature Pittosporum tenuifolium 'Silver Sheen' I am surprised because this is categorized as shrub and it is so big and tall and looks like a tree

Just looking at the leaves, I thought it may be in the populus genus (poplars), which is supported by the "little fruit that look like tiny blackberries" if this picture was taken earlier in spring, when these trees flower. I could imagine someone finding the male catkin(a type of flower cluster) to resemble a dense cluster of black berries. I've attatched a picture of a male Eastern Cottonwood(Populus Deltoides) catkin. Poplar catkins are imperfect, the male and female catkins occouring on seperate trees. Otherwise I would go with shaxhome's guess of Mulberry, although the leaves don't appear to be lobed. This post was edited by Pontederia on Sun, Jun 29, 14 at 1:08
