About the Rock Garden 

The Alpine and Rock Garden collections are made up of over 7,000 plants. They're planted permanently outside on Kew’s one and a half acre Rock Garden, in pots in our half acre Alpine Nursery, and as permanent and changing displays in the iconic Davies Alpine House. 

The Rock Garden dates from 1882 and is built of Sussex sandstone in the traditional ‘English’ style. It's laid out geographically with six major regions being represented. 

Each area is planted with typical rocky habitat species; plants found in gorges, coastal cliffs, alpine meadows, montane forests and also above the tree line are amongst those grown. 

About the Davies Alpine House

Opened in 2006, the Davies Alpine house is designed to provide the best conditions to grow and display a range of bulbs, mountain and mediterranean plants. 

This glass house has permanent planted areas and pot grown subjects supplied by the Alpine Nursery which are changed twice a week.

In addition to supplying display plants, the Alpine Nursery cultivates plants for scientific research.

The plants grown in the Nursery range from bulbs of the central Asian dry lands to those that inhabit the Cape of South Africa, from compact high alpine cushions and silver saxifrages of Europe to perennials and sub shrubs from the mediterranean basin.
