Onion grass is very similar to garlic, onion, and chive. They are all part of the bulbous family. Used carefully it can add an incredibly realistic "wild" element to your artificial planting.
Incredibly realistic, high quality artificial grasses display best in non-complex plantings using smooth sided planters, preferably in neutral colours.
Whether for home or business, why not combine several mixed foliage planters to form stunning yet unobtrusive displays?
