Purple-foliaged groundcover for perennial bed
I'm filling a bed with some lime-green foliage accents and I thought some purplish groundcovers would be just the thing.
Some of the bed is in full sun and some of it is in part shade; the soil is good and kept fairly moist but not soggy. I have a rose, salvias, geranium, salix purpurea (in the wettest section, by the downspout), and hosta.
I like finer-textured groundcovers, in most cases, that grow around other plants and form a "carpet" without competing. The only two purple species that spring to mind are New Zealand Brass Buttons (have that, what a cool plant) and ajuga (can anyone recommend the purplest ajugas?). Any other ideas?
