Butch, have grown hosta under walnut for years.  
Actually planted the Carpathian walnut for both shade and nuts - it is the one that pops the shell when the meat is ready to eat. Unfortunately, the squirrels have better ears to hear when the shelled nuts hit the ground.

This follows my theory that this site should teach and

Here is what I found which says I was wrong. At this
site are listed plants that have grown under black
walnut tree. Hosta is listed as a plant that is not
affected by the juglone.


"The roots of Black Walnut (Juglans nigra L.) and
Butternut (Juglans cinerea L.) produce a substance
known as juglone (5-hydroxy-alphanapthaquinone).
Persian (English or Carpathian) walnut trees are
sometimes grafted onto black walnut rootstocks. Many
plants such as tomato, potato, blackberry, blueberry,
azalea, mountain laurel, rhododendron, red pine and
apple may be injured or killed within one to two
months of growth within the root zone of these trees.
The toxic zone from a mature tree occurs on average in
a 50 to 60 foot radius from the trunk, but can be up
to 80 feet. The area affected extends outward each
year as a tree enlarges. Young trees two to eight feet
high can have a root diameter twice the height of the
top of the tree, with susceptible plants dead within
the root zone and dying at the margins."
