Sedum hybridum 'Immergrunchen' is a hardy, drought-tolerant stonecrop in the Crassulaceae family, native to Siberia and central Asia. It evolved in rocky, cold terrain with poor soil and harsh winters, which is why it performs with such ease in gardens and containers across a wide range of climates. "Immergrunchen" refers to its evergreen quality, keeping a neat appearance year-round.
It forms a dense, clumping mat of small, fleshy leaves with toothed edges that hold a glossy green color through most seasons. The trailing, clustering stems spread steadily to create a ground-hugging carpet, making it excellent for filling gaps along borders, slopes, and rockeries. The compact layering of stems creates texture even when not in bloom, and leaves are firm enough to hold moisture efficiently in dry conditions.
Sedum 'Immergrunchen' produces small, yellow star-shaped flowers that typically appear in summer, bringing bright color to the green foliage. The blooms are numerous and attract pollinators, adding seasonal interest. The evergreen foliage keeps the plant looking tidy long after the flowers fade.
It handles balcony wind and indoor heating without trouble, and you can leave it up to ten days without water. Move it outside in summer and back inside when cooler weather arrives, or keep it outdoors year-round if you live in a colder climate. It is non-toxic to cats and dogs, so pet owners can grow it without concern. You can propagate it easily from stem cuttings by snipping a healthy piece, letting it dry for a day or two, then pressing it into well-draining soil.

Sedum hybridum 'Immergrunchen' grows well in full sun to partial sun and handles direct outdoor sun well, though intense south-facing indoor windows can cause leaf scorch.
Water it every 10-14 days during the growing season, letting the soil dry completely between waterings, and reduce to once a month or less in winter.
Sedum 'Immergrunchen' does best in gritty, well-draining soil such as cactus and succulent mix blended with perlite or coarse sand in equal parts.
It is frost tolerant and handles temperatures down to approximately -30°F, surviving hard winters without protection in colder regions.
