I agree with Sue, I do have Lamium galeobdolon and Geranium macrorrhizum in my shady garden. Both are very tough, vigorous in spreading in even the most unfavorable conditions like dry and shade, That's why I use them in spots where no other plant wants to thrive and they're doing a good job. Same counts for Hedera helix, but like Sue says maybe not hardy for your zone.
