I've been searching for shrubs that would be beneficial for
established (or attract new) wildlife to the area, particularly birds.
This area is zone 5, nw NJ, mountainous, very acidic and heavy clay
soil. The immediate area they would be planted receives about 6-8 hrs
of sun per day in summer, but was also considering beneficial shrubs
for partial-sun areas.
You might want to consider myrtle (though it's more of a tree than a bush).
We've got a couple in our yard and the birds absolutely love the berries.
