Interesting Notes about Black Walnut:

This nut-producing tree grows very tall, in fact, there is a reported tree that is measured at 112' tall by 144' wide.  It has a tap root which makes it somewhat challenging to transplant.  It takes a few years before the tree produces any fruit and about 20 years before the tree is in full production.  The walnut tree produces a chemical which inhibits the growth of some plants in the nearby landscape or garden.
