There are not a lot of annuals that do well in
shade. Here are some I use.

Coleus
Impatiens
Pansy/viola (usually don't make it past Mid July)
Begonia (fibrous, bedding type)
Browallia
Caladium (tubers)
Lobelia erinus
Monkey flower (mimulus)
Forget-me-not (cut back by half when they go to seed,
and you will get more bloom)
Baby Blue Eyes and Five Spot (Nemophila) native wildflowers
but will not get thru summer
Ageratum

Emilie
NorCal zone 8
