Full Shade Zone 5
What type of perennials and shrubs to plant in a full shade area. The back of my home faces north, so if it gets sun it gets it before I'm even up! I have planted a fern, does fine, some hostas, okay, but I need some ideas. I've planted trillium there, didn't flower this year. Coral bells, didn't die, but didn't do much else either. Help! Thanks.
