I just discovered this groundcover perennial this 2020, planted at a rest stop along Route #1 in central Delaware. I had known of two other Spurge species as somewhat common perennials, but not this one. This Wood Spurge is native to Europe and Turkey. This natural variety of Robb's Wood Spurge is the groundcover form that spreads slowly by rhizomes ( underground stems). It is easy to remove but one must be careful of the milky sap that can be irritating to many people's skin. The leaves are dark green, leathery, and evergreen. It forms flower stalks that bear yellow-green disc-like bracts with tiny yellow flowers in front of the bracts. It grows best in part-shade to full shade and in dry to moist soils. It is noted as doing well in the dry shade of trees. North Creek Nursery in southeast Pennsylvania sells this plant. Most conventional nurseries don't carry this plant.
