I grow a variegated version of fallopia japonica which in the many gardens I've grown it has not been invasive. It's early spring growth is a lovely coral color. The variegation is pretty impressive and it flowers late in the season. Unfortunately this year it has been ravaged by Japanese beetles. But I seem to be having more than my fair share of those this year!

Hostas. As long as you don’t have slugs and snails.

Persicaria virginiana 'Painter's Palette'

Scrophularia auriculata 'Variegata'

Polygonatum odoratum ‘Variegata’

Polemonium reptans 'Touch of Class' and 'Stairway to Heaven'

Heliopsis 'Lorraine Sunshine'

Lysimachia punctata 'Alexander'

Acanthus 'Whitewater'

many cultivars of Pulmonaria, Lamium maculatum, countless different hostas, many brunneras and a whole bunch of carex and ornamental grass cultivars will also offer white/cream and green variegation. A bunch of groundcovers as well.

Ooop, sorry I should have mentioned need those that prefer full sun.

I wasn’t successful with Heliopolis Lorraine Sunshine, and to me the foliage looks diseased. I prefer plants with borders or stripes of white like Iris pallida, Caryopteris Snow Fairy, or variegated dogwood.

There are a couple of Daphnes, Briggs Moonlight and x transatlantic a Summer Ice.

A number of both grasses and sedges are variegated, but I don’t know if any of the Carex like full sun.

I have seen several different variegated Sedum, both low growing types and some that grow larger like Autumn Joy.

Some varieties of sage and thyme are multicolored leafed and winter hardy in zone 6a; spurge, red twig dogwoods.

My favorite variegated sedum is September Charm. It is a compact grower so does not usually need to be pinched and does not splay. Another favorite is Spirea 'Painted Lady', wonderful yellow splashed leaves. Also a compact grower.

Is the "September Charm" sedum green and yellow or green and white variegation? I have a "Pink Chablis" variegated sedum which I love but they are hanging on by a thread, a beautiful but weak cultivar that's for sure, and no longer available for sale. So if I could find something similar that would be great -- but I'm not a big fan of the green and yellow variegation, it just doesn't do it for me.

I would call it creamy white. Definitely more yellow than Pink Chablis but also much more robust. I too have Pink Chablis and love it but I don't think there is a weaker growing sedum out there.

"I don't think there is a weaker growing sedum out there."

With that I agree. Too bad, too -- it really is a great-looking plant.

One of my favorites is Phlox Norah Leigh. It looks great all season and I have never had one plagued with powdery mildew.

Another stellar performer here is Caryopteris White Surprise

Others...Phyostegia virginiana Variegata, Eupatorium fortunei Pink Frost (although that may be more cream than white).
