To expand our understanding of the experience of growing penstemons in all parts of the US, Canada and Europe I have written a brief survey. I am asking all members to fill it out. It is easy and quick to complete. The survey lists all the species that are presently under cultivation and asks you to check ‘easy’ ‘moderate’ or ‘diificult’ to grow if you have grown (or tried to grow) that penstemon. And if you have time, the survey also requests your location and to write just a little about your gardening environment — soil, moisture, temperatures, etc.
Many many thanks. Barbara Lewis
