Scatter your inhibitions about gardening to the wind, and opt for a planter brimming with artificial Zebra Onion Grass. The overall appearance of this ornamental grass is exotic and appealing with a resemblance to something you would see in the outskirts of African jungles. While the name conjures mental images of striped creatures grazing on the sweet grasses of summertime plains, the actual reason for this plant's namesake are the cream-colored, gold-tinged stripes on every grass blade. These faux houseplants are lengthy, reaching heights of either 4 or 6 feet - and you can nestle their sturdy, black base within a residential or commercial planter.
