compatable with black walnut
What shrubs (~5' max height) can I plant under a Black Walnut tree? I want to create a dense bird cover planting.

I believe you can plant hydrangea, forsythia and hibiscus near black walnut. Many trees, though they may reach over 5 ft., are compatible as well: arborvitae, flowering dogwood and Japanese maple are a few.
