Partridgeberry

I like our pachysandra and hosta. Ferns that come back and look great in batches are tassel fern and autumn fern.

Ceratostigma plumbaginoides is one of my favorite groundcovers but it is not evergreen.

I am a bit unclear on what you want. Do you want something that can be walked on directly? or along the path? or between stepping stones? Also, where are you? What is evergreen in NH is not the same as what is evergreen in WA or TX.

It would not be walked on but would lay beside a concrete path directly under a wall. The strip, now covered by weedy growth, is about a foot wide. I'm in Oregon.

Veronica 'Georgia Blue' is evergreen in OR.

Lady's Mantle

Japanese Pachysandra comes in variegated as well as green

Lamium might work, but you will need to check more locally as to whether it's evergreen.

Golden creeping Jenny only if it can be prevented from escaping (as in pavement or buildings on all sides)

European ginger and some of the forms of native ginger with variegated leaves such as Asarum hartwegii.

I don't know whether it would b evergreen for you, but Hakone grass has slowly expanding clumps, and both the gold and the variegated varieties are lovely.

Perennial Geraniums such as Biokovo (I think there are a couple of others as well) are great taller ground covers, and are probably evergreen in your area.

Some of the shade-tolerance sedges (Carex) such as Ice Dance have variegated or colored foliage and will spread.

Chinese Astilbe (Astilbe chinensis var. pumila or A. c. var. davidii for two examples) is a spreader unlike most Astilbes.

Woodland Phlox (Phlox divaricata) might work for you but is another that I don't know whether it's evergreen.

If partridge berry (Mitchella repens) will grow in your area, it's a great little plant.

Mazus reptans is yet another that I don't know whether it will be evergreen for you.

My preference is usually a mix of plants that will be ornamental even when they aren't blooming, and so I like variation in foliage texture, color, and size, so if it were my space I would use a mix of low and taller, some variety of color, and some that bloom. If you go this route, use repetition as you move down the bed.

A couple of things I forgot:

Some Epimediums are evergreen. Some are clumpers and some are spreaders.

I would be a bit worried about vinca since it can be a trip hazard unless you are willing to keep it well trimmed to keep it off the path.

Mulch will be your friend to keep the weeds down while the other plants establish and expand. If you put down a layer of several sheet of newspaper and wet it down to hold it in place, you can plant through it and then mulch relatively thickly. If you aren't going to plant all at once, you can either do it a bit at a time or weed it all, put down the newspaper layer or a single layer of corrugated cardboard, and then mulch the whole thing. When you are ready to plant, just pull aside the mulch, cut through the newspaper or cardboard, and plant, and then pull the mulch back to near but not against the plants.

I assume you're in western Oregon........
