Allegheny Spurge is a much preferable alternative to Pachysandra Terminalis. That said, it spreads extremely slowly growing beneath a black oak in my woodland garden. The plants that come up remain for many years but I still only have very few per each original planting after 3-4 years. Although the leaves look very soft, they're actually very rough and can hold up very well over time. For me it's more of novelty plant than a real groundcover.

An attractive native semi-evergreen groundcover. Most years it's evergreen here in Boston Z6a. More clump forming than P. terminalis, and with a much coarser foliage texture.

The silvery spotting/overlay on the foliage is very attractive, but does not appear till the weather cools in October, when the background color of the leaves takes on a darker, purplish cast. It usually remains attractive here through the winter till the new foliage appears in spring. The degree of silvering varies from clone to clone.

The flowers generally are not very showy, and are often lost beneath the foliage. I can't smell their fragrance unless I lie down and sniff them.

It is a nice native groundcover. I first saw it growing at Morton Arboretum in Lisle, IL, west of Chicago, where the topsoil is most often silty, and usually with a pH range of 6.8 to 7.1. The soil does not have to be acid, just moist and well-drained. I planted a clump right next to my house foundation in se PA where my soil is a good quality clay with a pH of 6.9. It has been doing well and is slowly expanding.

First grew this plant in the mountains of SW Va. (z5) It performed well in sun and shade, though the ones in sun were a little stunted. I now have it in the D.C. area (z7), where it must be in shade with adequate water. All the ones I planted in dry shade (maple shade) have declined terribly; even w/ irrigation.

This is one of my favorite groundcovers...evergreen in our zone 6B, new green foliage, greyish green mottled rosettes ongoing, purplish fall color, and a spiky pale pink flower. Slow to get started, but thick and matting after the second to third season. A beautiful addition to the native garden, but at home as a shady edging anywhere! Seems happy in any soil and even in dry conditions.

Slower-spreading and arguably prettier than its Asian cousin Pachysandra terminalis it can be argued that this lesser-known native should get more attention from gardeners looking for a well-behaved groundcover. I planted a few plugs last spring in my woodland garden, and am pleased with the slow-but-steady spreading nature of it.

I didn't know to look for the silver/pewter pattern on the leaves last fall, but I've planted several more pots of P. procumbens in a prominent bed near our front sidewalk, and I'm looking forward to seeing how it does year-round.

This clump-forming, 36" wide native is composed of pewter-green foliage on long prostrate stems. In spring, stalks of 4" tall, white bottlebrush-like flowers arise from the center of the clump...great when used in a mass in the woodland garden.
