There are a few options, and we'd recommend using a mix of species so that the planting is more resilient and not prone to the same stress, pest, or disease issues in case there is a future outbreak that causes temporary damage. (Plus, with more species, you can have more seasonal variability and interest as things flower at different times.)

There are two species of Pachysandra grown in Maryland -- the more widely-used one (only due to familiarity and being more evergreen) is Japanese Pachysandra, Pachysandra terminalis, which can be invasive and is not recommended. The regionally native species (it's not native within Maryland, but is found in the eastern U.S.) is Allegheny Pachysandra, Pachysandra procumbens. Although it can be fairly evergreen as well, the leaves tend to blend-in more with fallen leaf litter because they have a mocha-brownish hue in winter, not rich green like the Japanese Pachysandra. Still, there are other great options besides any type of Pachysandra, which you can explore in our Groundcovers web page. It doesn't have exhaustive lists of species to consider, but does share some ideas in various categories based on growing conditions and if plants are native or not.
