A Society Charter: Based in Edinburgh, but with members nationwide, The Caley welcomes anyone interested in gardening, be they amateurs or professionals, beginners or experienced gardeners.

Basic guiding principles of the Society are set down in bye-laws originally approved in 1877 and continuously revised and refined up until the present day.

The Caley "Charter" addresses the current purpose of the Society and emphasises which activities are required to ensure its continued well-being. The Charter is therefore:

1. To recognise and promote horticultural excellence and achievement in Scotland.

2. By maintaining a busy programme of activities, and marshalling all available expertise and resources, to ensure continued functioning of the Society, a healthy membership, and maximised benefits for its members.

3. To co-ordinate national events and, by closely associating with all gardening societies and organisations, to represent the horticultural movement in Scotland.
