Use these oval herb markers to ensure that you find your perennial plants when it is time to remove winter mulch each spring and throughout the season, they will guide your culinary or gardening assistant to clipping a fresh bunch of the herb you asked for. Each marker has an aluminum oval face with an etched illustration and herb name and a metal stem with stabilizing cross-piece that can be pushed into the ground. Standing about 8 in off the ground, the markers are visible even after plants become full and lush.
