6" hanging basket. Zebra Inch Plant (also called Silver Inch Plant and Wandering Dude) is a tender perennial, creeping vine that is native to Southern Mexico and Guatemala. It is a very tough plant and can do well in almost any condition indoors as long as it is not overwatered. Zebra Inch Plant also makes a great "spiller" for outdoor annual containers.
