We are proud of our colleague, Professor Emeritus Wayne Armstrong, who has amassed an enormous amount of botanical information and other natural phenomena for which he is world-renowned. This information includes a thorough discussion of the plants and history of the arboretum.

This information can be found on his website, Wayne’s Word.
