Updated Version of Handbook of Cycad Cultivation and Landscaping
The Cycad Specialist Group is pleased to present Volume 2 of the ‘Handbook of Cycad Cultivation and Landscaping’, a comprehensive guide for cycad enthusiasts, horticulturists, and conservationists.
This guide consolidates essential knowledge about cycad care, propagation, and conservation, providing accessible insights for botanical gardens, nurseries, and serious hobbyists. It features practical tools such as the Decision Table, which offers at-a-glance advice on soil requirements, irrigation, pest tolerance, and landscaping considerations. The handbook also addresses the challenges of growing cycads in various climates and environments. A supplemental spreadsheet for the handbook with data for different species is provided here.
We hope this resource inspires and equips readers to contribute to the understanding and protection of cycads worldwide, fostering appreciation for their unique beauty and ecological importance.
This is the Second Edition of the original handbook published in 1995, available for download below.

Get to know the world’s most endangered plants – an introduction to cycads
CSG members Nathalie Nagalingum and James Clugston have collaborated on the following video introduction to cycads:
“Cycads are a model group for both education and science communication because of their incredible evolutionary history, ancient origin, and conservation threats. Cycad are at risk due to illegal poaching, over-collection, and habitat loss, and communicating these threats is very important to cycad survival. In a highly connected world, science communication is vital and online media can quickly get the message across.
This video i provides an informative introduction to the cycads for scientists and non-scientists alike. The video introduces the Cycad Specialist Group (CSG), and explains cycad history, morphology, diversity, and reproduction. We hope the video will become a resource for all those who have an interest in getting to know and conserving the cycads.”
