I'm looking for a plant that will grow fast enough and be clippable in one season as an annual, or a perennial that is hardy to USDA Zone 4, to make a low hedge (not boxwood). I saw this low clipped hedge at a public gardens near the St Lawrence in Ontario, it reminds me somewhat of savory but if it had any flowers to help ID it they'd been clipped off. Does anyone have any idea from the leaf arrangement what it might be?
