New RHS Index of Garden Plants

This checklist of garden plants in Europe, North America, Australia, New Zealand and South Africa has been researched by 250 botanists worldwide.

It also contains 22,000 botanical names that are no longer officially in use and 10,000 popular names.

An illustrated botanical glossary explains all the terms used to describe plants, and lists the most commonly encountered Latin names and their definitions.

Every name (including cultivars) is followed by a brief description, the plant's distribution in the wild and its climatic zone, supported with maps for Europe and North America.
