I'm new to the Island (oahu) and I keep seeing these trees, unfortunately only when I'm in the car and don't have a chance to stop and look at the properly.

They have light green, almost silvery leaves and very pale grey bark. The trunk and branches are twisty and almost look vine-like. I find them to be exceptionally attractive, and I'd like to get a sapling (if possible) or at least know WHAT these trees are called!

All my efforts to Google have been to no avail, I am hopeless with search engines. I just cannot phrase properly.
