It's a Schefflera arboricola, or dwarf umbrella tree. They are from Taiwan originally and while can handle 30's, outdoors will kill it.They are very tough plants and tolerant of poor soil, poor light, etc. Years ago I used them in research addressing the effects of certain types of radiation.They will flower if given lots of light.
Is it just me, or is this guy a plethora of information on just about anything???!
