Allegheny Spurge, Pachysandra procumbens, is a perennial native to woodlands of the Southeastern United States. Allegheny spurge prefers rich soils, average moisture, and full to part shade. Plants slowly spread by rhizomes, creating a dense carpet of groundcover. Small, fragrant, white flowers emerge in spring. Allegheny spurge makes an excellent groundcover for shady areas. May be evergreen in warmer climates.
