Help needed with planting a berm in the shade
I am looking for ideas on what to plant on a berm that is roughly 100' long x 8' wide x 4-5' tall. This berm is near existing Norway pines and is shaded. I have planted another 30 pines on the top, but I would like some type of ground cover or flowers to plant (by seed hopefully). The berm is located on one side of our lot near Minneapolis, Mn. The berm is a dirt/sand mix from excavating an addition (probably 8-10" black dirt over sand. Underlying soil is sand.
Thanks for any ideas you can share,
