Thanks to Bob McFarlane who had the vision of an updated website and to Louise Parsons, who designed the Society's first website.

Of central importance to the breadth and depth of this Cultivation Section are these authorities on penstemons who generously shared much of their material. They are Ellen Wilde, Dee Strickler, Bob Nold, and Dale Lindgren.

We would also like to acknowledge the authors of additional valuable print sources used for reference. These include Jean Heflin, David Way and Peter James, and Noel Holmgren.

Appreciation is also extended to the numerous authors whose work appears in the Articles Section. Most of these articles first appeared in the The Bulletin of the American Penstemon Society, a rich resource of information dating from the 1960s onward. .

Many photographers whose work appeared on the Internet kindly gave permission to use their pictures.

A special Thank You goes to the Cultivation Expert Panel. These individuals have patiently and graciously provided essential editing for much of the material in this section.
