A moss to brighten a dark spot in the garden

We spotted this moss at our local nursery. Golden spikemoss, Selaginella kraussiana 'Aurea'. The unusual golden color was very attractive and we thought it would brighten our north facing, shaded dark spot next to the garage. We bought three and they've worked out quite well, growing in size and thriving without much care. I thought the moss would require frequent watering but even in our dry August it did not wilt nor showed any signs of stress. It's also hardy to zone 6 so I hope it will make it through winter unscathed.

I apologize for the unfocused photos.
