Carson has been a member of the ICPS since 2007. His relationship with CPs focuses on the ornamental horticulture of Sarracenia.

Carnivorous Plant Newsletter of Australia

The International Carnivorous Plant Society is pleased to host an archive of CPNA newsletters.

The Carnivorous Plant Newsletter of Australia was edited and published by Ken and Susan Hatley of West Australia from June 1979 until March 1981. This publication died a natural death in March 1981 due to both a lack of contributions and because the editors opened a large retail nursery in Perth that consumed their time.

Read the issues is in our historic documents section.
