Pachysandra procumbens (Family Buxaceae), commonly known as Allegheny spurge or mountain pachysandra, is a species of flowering plant native to the southeastern United States. Many thanks to Pete, who turned us on to this small group of plants that was found in Forest Park in St. Louis City. Not native to this region, this was obviously planted there at some point.
Pachysandra procumbens has a delicate and unique appearance. Its leaves are larger and serrated, with a distinct purple-bronze coloration in the spring that matures to a glossy green throughout the growing season.
In the spring, Pachysandra procumbens produces small, white, bottlebrush-like flowers that are highly attractive to pollinators such as bees and butterflies. These flowers give way to small, berry-like fruits that add further interest. This plant prefers moist, well-drained soil and is partial to full shade. The inflorescence are small, but definitely worth a close look.
