Use Pachysandra procumbens (Allegheny Spurge) to carpet shaded beds with a refined, woodland look. You get prostrate stems topped with matte, blue-green leaves that often show silvery mottling, plus lightly fragrant white flower spikes in spring.
Plant it where your garden gets partial shade to full shade, including dappled light under trees and shrubs. It performs best in moist, well-drained, organic soils and appreciates an acidic to near-neutral site. In the coldest areas it can die back, while in milder climates it can be semi-evergreen.
Expect a low, tidy groundcover that typically reaches about 6-12 inches tall and spreads by rhizomes to fill in bare soil over time. For a quicker knit, set plants about 6-12 inches apart and keep the bed evenly moist during establishment.
Once rooted in, it tolerates short dry spells better than many shade groundcovers, but growth is best with consistent moisture. Mulch with leaf mold or compost to mimic its woodland habitat and to protect shallow roots from heat swings.
Maintenance is simple: pull stray runners if you want sharp edges, and shear or thin lightly in late winter to refresh the planting and remove any winter-damaged foliage. Provide good air movement and avoid waterlogged sites for the healthiest patch.
