Northern Sea Oats or Canada Wild Rye?

However, I probably wouldn't put grass there. My parents use ferns for a similar purpose. Also, Rose of Sharon seems to have accidentally suckered into some shaded spots behind an evergreen hedge, and inexplicably survives. Lily of the Valley also likes shade and has pretty flowers. If you found something that was a nitrogen fixer, it could fertilize the Hydrangeas. Jersey tea is a somewhat shade tolerant nitrogen fixing shrub. (Ceanothus americanus). Might need more sun then you have. You could get a flowering or nitrogen-fixing vine to climb the fence. A vine could get sun from the top of the fence and the other side. (Be careful to check if the vine you pick is invasive in the area.)
