The variegated Fatsia “Camouflage” variety will be perfect here. Its light green variegation on the leaf will brighten the dark area. It is a shade plant that will grow about 8 feet tall under the maple’s canopy and wide enough to provide the privacy between neighboring yards. The ferns too will love this shady space. It is fairly dry, being under a huge maple, so I will choose ferns that like their roots a little on the drier side. It would not make sense to plant fern species here that need constantly moist soil. Right plant, right place makes a gardener’s life easier.
