Please suggest some perennials to plant on the north side of my home.
The following gives several lists of plants that grow well in shade. If you have big eaves or gutters that divert the water from your planting area you probably have dry shade. Many of the plants on the "dry shade" list also can grow in wetter areas. http://www.extension.umn.edu/garden/yard-garden/landscaping/best-plants-for-tough-sites/
Some of my favorites on north side of my house and garage (some areas are wetter than others) are astilbes, hellebores, hostas, ligularias, bleeding hearts, thalictrum (meadow rue), cimicifugas, brunneras, heucheras, primroses, lungworts, bergenias, epimediums, Japanese yellow waxbells, Solomon's seals, and tiarellas. Many garden centers group their plants by sun/shade requirements. Sometimes it is best to go there to see what plants you can actually find.
