Geranium phaeum is good, but it spreads ike a rampaging forest fire throughout the rest of the garden - be warned! I now cut it down at the first sign of seed heads, and even so it pops up everywhere, and is too tall and big to allow it its head as I can do with other plants.
Also for dry shade, pachysandra is very good, nicely shaped leaves and white spikey flowers.
This next bit is for gardeners with a very strong constitution. We have a very large and well loved red sycamore half way down our garden - under which little will grow. Please sit down now if you are likely to faint ....... I have planted variegated ground elder there, it lightens up the area and looks wonderful. As it has to really struggle for life it does not spread, it had s been there for about 10 years now, and remains more or less in place. It is never, ever allowed to flower, it does occasionally try to hijack a lift out in a nearby pot, but so far I have spotted it and stopped the escape. This is not something I would suggest except for the darkest, dryest & most inhospitable of places, but in these it really does do a great job. I do have its weedy first cousin in another part of the garden, that is not welcome and seems to be trying for world domination - but we all know about that one.
