Plants

Kew Gardens has one of the most diverse collections of living plants of any botanic garden in the world.

Callistemon citrinus,  the bottlebrush plant

From the tropics to the treetops

A world-famous living plant collection

Our magnificent scientific collection contains plants from tropical, temperate, arid and alpine climates. Our expert horticulturalists grow them both in our gardens and in controlled conditions within glasshouses and nurseries.

What is a living plant collection?

A living collection is what sets a botanic garden apart from a park or public garden. 

It is a group of plants grown especially for research, conservation, education purposes or ornamental display.
