About
Corsican stonecrop (*Sedum dasyphyllum*) is a tiny, mat-forming succulent with bead-like leaves that blush rose in sun, rooting along stems as it creeps over rocks and wall caps. Individual rosettes are only millimeters across, but colonies spread widely in favorable cracks. It is a classic green roof and crevice plant for sharp drainage. In subtropical and tropical Americas it thrives in bright, breezy, fast-drying microsites—humid shade invites rot, so give it rooftop, path edge, or hypertufa conditions. ☀️💧 **Sun and Water Requirements:** Full sun to very bright shade. Extremely well-drained gritty mix; essentially no irrigation once established except during prolonged drought in containers. ✂️ **Methods to Propagate:** - **Stem fragments:** Press broken pieces onto moist grit; roots form at nodes in warm weather. - **Offsets:** Detach rooted mats from mother colonies in spring and press into crevices. 🌾 **Best Use Timing:** Refresh mats every few years if centers thin out—replant vigorous edge growth. Avoid heavy foot traffic; best viewed, not stepped on.
Permaculture Functions
- **Ornamental: ** Living grout between pavers and stones reads as deliberate, not neglected.
- **Ground Cover: ** Succulent carpet excludes some weeds on lean soils where turf would demand absurd inputs.
- **Erosion Control: ** Interlocking roots and stems armor thin soil on slopes and wall tops.
- **Water Retention: ** CAM succulence buffers short dry spells without sprinklers.
Practitioner Notes
- Overwatering kills faster than drought—winter wet on flat trays rots pearls in days.
- Pieces root from stem fragments—plug holes by tucking broken stems into grit after storms.
- Mealybugs hide in leaf axils—alcohol detail beats oil smother on tiny stacked leaves in hot sun.
- Color shifts copper under stress—back off water if you want tight blue-gray mats, not flabby bronze.
