Climbers would be some clematis ,honeysuckle.Perennials like dicentra ,hostas,heuchera,tiarella,ferns .It really depends on lots of factors such as is this dry shade and your soil type and how much shade ect ect.

Some of the perennial geaniums, bedding begonias (the small fibrous rooted ones, not the corms) Alchemilla mollis if you have plenty of room as the self seed.
