Most rhododendrons and azaleas are killed by juglone, the toxic agent in black walnut. I know that a couple rhododendrons and azaleas are not killed. They include:
Rhododendron periclymenoides
Azalea 'Gibraltar'
Azalea 'Balzac'
Fortunately walnut leaves aren't nearly as big a problem as the roots and hulls.
Conversely, some rhododendrons will kill plants planted near them. That is one thing that is so insidious about R. ponticum in England. The ponticum runs rampant and kills some of the native plants.

What tree grows walnuts?
These plants grow well in a bed around the trunk of a large black walnut tree in my garden in central Maryland (Zone 7): Black-eyed susans (rudbeckia) ; daylilies (hybrid & common), hostas (various cultivars), impatiens, tradescantia, carpet bugle (ajuga reptans) Also growing well nearby (under walnut tree canopy but about 4 feet from the trunk): two sedum cultivars, monkshood (aconitum carmichaelii), honeysuckle cultivar; pink turtleheads (chelone lyonii), climbing eunonymus, Virginia bluebells, None of these plants are adversely affected by the tree's supposed toxins.
Why will plants not grow under a black walnut tree?
Walnuts release a chemical into the soil called juglone. Juglone is present in all parts of the tree, but can be especially high in the roots and walnut hulls. The highest concentration in the soil is directly beneath the canopy of the tree, but it can be present in lesser concentrations anywhere the roots are present (which can be out as far as the tree is tall). The presence of juglone can also be affected by soil type, with sandy well drained soils tending to have less of it present. Juglone can be toxic and even fatal to some plants, while others don't seen to be affected by it. Affected plants show signs of wilting, yellow leaves, stunted growth, and eventually death.

What is the name of a walnut tree?
That's a good question, because Ive been wondering the same thing. "Supposedly" we have one, that's not allowed to be cut down because its "rare," but I cant find a picture that looks anything like it. As of right now, all its doing is giving free access to the roof of the house. Its tall and lengthy, scrawning looking as if it grew as a weed into a tree. The bark is very pale. Its kind of ugly looking, to be honest. Hahah. If you find out, email me at sofaraway89@juno.vom
