Pachysandra procumbens Michx.
Allegheny Spurge, Mountain Spurge
Buxaceae (Boxwood Family)
USDA Symbol: PAPR7
Mountain spurge or Allegheny spurge is a low perennial, spreading with long rhizomes. Toothed leaves crowd near the top of somewhat fleshy, 6 in., erect stems. Fragrant, white flowers cluster in a spike, the many staminate flowers above, the few pistillate flowers below. Leaves and stems are evergreen. Once the new shoots mature, the previous seasonís growth disappears. Leaves have scalloped margins and are marbled with silver and purple.
Mountain Spurge is an excellent ground cover for shady areas. It is considered more attractive than the over-used, Asiatic Pachysandra terminalis. The native species grows slowly and will not take over like P. terminalis.
