Overview Botanical Name: Sedum takesimense ‘Atlantis’ (sometimes sold as ‘Atlantis’ Stonecrop) Common Name: Atlantis Stonecrop Plant Type: Low‑growing succulent perennial / groundcover Mature Size: Typically 4‑6 inches tall (10‑15 cm) and about 10‑12 inches wide (25‑30 cm) in spread. Hardiness: Rated for USDA Zones 4‑9 in many sources. Note: In ideal conditions (very well drained, sunny site) it may perform in early Zone 3 with caution. Light & Site Requirements Requires full sun for best performance — 6+ hours of direct sun recommended. Soil: Prefers very well‑drained soil, average to poor fertility. Avoid heavy, wet soils especially in winter. Soil pH: Neutral to slightly alkaline soils are acceptable. Excellent for rock gardens, edging, containers, or as a mat‑style groundcover. Watering & Maintenance At planting & establishment: Water to get settled, but ensure drainage is good. Once established: Drought tolerant; minimal watering required. Even periods of dry are well tolerated thanks to succulent nature. Avoid overwatering especially in winter — wet conditions can harm succulents like this. Minimal fertilizing needed — lean soils are preferred. Rich soils may cause lanky growth. Maintenance: In early spring you can trim back any damaged or mushy growth from winter. Cold Climate / Zone 3 Considerations Because plants are rated at Zone 4 minimum, be extra sure to select a sunny, well‑drained site if you are in Zone 3. Avoid low spots where water might accumulate or freeze. Good drainage in winter is key. Snow cover helps protect shallow groundcovers — but ensure excess moisture is not trapped. Best used in raised beds, rock gardens, slopes, or containers that drain well. Special Features & Landscape Uses Gorgeous variegated foliage: Dark green centers with wide creamy yellow margins; in cooler weather margins may blush pink. In summer, produces small yellow star‑flowers above the foliage.
