...a very special person and plantsman. Paul introduced me to a unique palate of material to meet the criteria of approaching a landscape project from an artist’s sensibility. What was really unique about Paul...on a series of wide ranging expeditions to locate and evaluate plant material, Paul wove a story for me...a history of plant life over the millennium...its botanical, cultural and social significances. It was a history of relevance for the uninitiated audiences of an art museum. Paul has added a richness to my view of landscape as a credible artists medium.
