Blue Muffin Arrowwood as hedgerow under a tall hemlock
I need to plant a row of shrubs on the edge of my zone 4 Vermont property to keep children from exploring a twenty foot slope down to a road. The edge of the slope is under a very tall hemlock and north of a hemlock/deciduous forest. The ground is covered in moss and there is enough sun for day lilies to blossom.
After talking with someone at the local nursery, I'm thinking of going with a combination of "blue muffin" viburnum and swamp azalea. Does this make sense? Would another combination of shrubs and plants work better in this space?
