Salvia spathacea. I have two of them that get more sun than they would probably prefer. It grows profusely under a canopy of oaks at Rancho Santa Ana Botanic Garden. Mine have survived temps down to 23 without damage.

My microphylla 'San Carlos Festival' is growing under a large S. mexicana, so sunlight is limited. It puts out plenty of pretty pink flowers throughout the season.

Salvia Miniata loves shade, I think the rule of thumb was the shinier/glossier the leaf the more shade it will take.

I will agree with the other postings. You can also try S.coccinea which comes in Pink,White,Red. Depending also
on which part of the country you are in some other idea's are.. Salvia x "Purple Magesty" and S lyrata (Light Blue
Flowers). If you don't mind annuals Salvia splendens comes
in all the colors you are looking for the blue splendens is new this year.

I grow my S. spathacea, guaranitica and elegans in fairly shaded areas and they do quite well. All seem to like moderate water, but not to be wet for extended periods. I think you can find cultivars of the guaranitica and elegans that would fit your color scheme.

I have a bed like yours. In this bed there are:
S. farinacea
S. lyrata "Burgundy Bliss"
S. nemorosa "Caradonna"
S. scabra
S. x superba "Blue Hills"
S. coccinea
S. uliginosa

Also in shady outer beds are:
S. buchanii
S. blepharaphylla
S. mexicana
S. melissadora

I have a rather large salvia mellifera (black sage) that's doing well in part sun. The blooms aren't remarkable, but I like the scent.
