John and Andrea each spoke for an historical and horticultural and educational seminar on a summer's day in Orefield, PA

I have drawn upon the wisdom found in many books for the notes that you find on these pages.  It is from standing on the shoulders of giants that I am able to publish such considered opinions and cast a much longer shadow.  I acknowledge these many authors and authorities from across the globe and time for all of the help that they have given to me.  More information may be obtained by following a few links to their own locations on the web.

The Brother Gardeners:  Botany, Empire and the Birth of an Obsession.  Andrea Wulf  http://www.andreawulf.com/andrea-wulf/about-the-brother-gardeners.html  One of the best books on the era of plant discovery.  So good that I should have written it myself.

The Founding Gardeners:  How the Revolutionary Generation Founded an American Eden.  Andrea Wulf  http://www.andreawulf.com/andrea-wulf/founding-gardeners-the-revolutionary-generation-nature-and-the-shaping-of-the-american-nation.html  Very local in its habitat and all about the Bartrams of Philadelphia.  See which, what and how many of John’s discoveries were used in the estate gardens of our founding fathers.
