If there’s a plant that refuses to quit, it’s Sedum ‘Immergrünchen’. This low-growing, fast-spreading succulent forms a lush carpet of bright green, fleshy foliage, creating a soft yet indestructible mat across the landscape. Its name means “evergreen,” and that’s exactly what it delivers—a fresh burst of green even when other plants fade. In summer, it’s dotted with tiny yellow flowers, bringing in bees and butterflies like a nectar buffet. Drought-proof, cold-hardy, and practically maintenance-free, this sedum is the perfect groundcover for sun-scorched slopes, rock gardens, containers, and anywhere you need life to thrive with zero effort.
