seeking shade plant recomendation

[sadie_sabot]

I have a shady spot in my shady yard, it gets very little sun. I'd like to plant some sort of perennial there, that is hardy enough to not get crowded out by weeds if I neglect it for awhile, is somewhat drought resistant since it gets hella dry in the summer, is not overly enthusiastic (I don't want it to take over the place!) and is good looking.

anyone have any suggestions? it's for a north facing yard in san francisco on the edge of the fog zone.
