That's a cultivar of the ordinary Umbrella Tree, Schefflera actinophylla? I saw something like that for sale one time but never took any notice of the name. Certainly a lot different to what I'm used to.
Sheffy's'll do that...we have a HUGE Dward Shef that has 'strangled' two Ohia (tall trees) and the limbs are very 'viney'...Also the 'Octopus Tree'...that Brassaica (sp?) sprouts everywhere and eventually strangles the host. Better build a hurricane fense around that baby and get some Pit Bulls!!!
