Known as Golden Oregano or Golden Marjoram, Origanum vulgare 'Aureum' is a showy edible but ornamental perennial herb that is perfect for use as a groundcover in partially shaded to shady areas. Its fragrant foliage turns a vibrant golden yellow to chartreuse during the spring and fall seasons. With foliage that grows only 4 to 6 inches high, it spreads fairly quickly to form a dense patch that lights up shady areas and tolerates moderate foot traffic. Clusters of small lavender flowers in summer attract butterflies. Get all the details below!
