Shade Gardening: Shady ground cover tolerant of imperfect drainage, 1 by Weerobin

We put in a new entry walk a few years ago.
I purposely had the stones placed slightly apart, so I could plant a fill-in ground cover.
I had planned to use dwarf mondo grass, as it has done well in other areas of my yard.
I thought the mondo would look great offsetting the harshness of the stone.
Unfortunately, the mondo grass idea hasn't worked out.
I tried it twice and it doesn't overwinter in this location.
It has overwintered fine in other locations in my yard.
So I presume it is due to poor drainage in the walkway.
Does anyone have any other suggestions of a shade-tolerant really low-growing ground cover which might fill the crevices between stones?
Here's a shot of the walkway. Alas, no sign of the prior mondo grass remains...
