About

Trees and Shrubs Online is a project to create a truly modern reference to temperate trees and shrubs. Currently there are articles for some 730 genera and 4,500 species, with each species article describing many subspecies, forms and cultivars. New material is being writen and old material rewritten. The first genus to have gone through this process is Stewartia, which stands as an example of what is to come.

Currently, the bulk of the text is derived from two sources: New Trees by John Grimshaw and Ross Bayton, commissioned by the International Dendrology Society and published by Kew Publishing in 2009, and W J Bean’s Trees and Shrubs Hardy in the British Isles, first published in 1914. The 'Bean' text is from the Eighth Edition, the last to be published, which appeared in four volumes during the 1970s, along with the Supplement by Desmond Clarke, published in 1988.

The International Dendrology Society is dedicated to promoting the knowledge of trees and shrubs and is pleased to be able to stand behind this important project. The IDS is raising funds to cover further development of this site. If you might be interested in sponsoring a genus or supporting the project in any other way, please do contact IDS at the email address below.

Using the site

The articles are organised alphabetically by genus, and then by species within each genus.

There are two main ways to find articles: you can use the Browse page to find genera and species organised alphabetically, or you can search.

To search, use the Search box on the Home page or the Search page, or select Advanced Search on the Search page for further options.

On pages with genus articles, there are links for the species in that genus, and with species articles links to the other species within the same genus.

To find plants in a particular family, use Advanced Search. The search will largely produce articles about genera within that family; these articles contain links to the species.

The International Dendrology Society conceived and continues to support this project.

The use of material from Bean's Trees and Shrubs has been enabled by the generosity of the publisher, Hachette UK (formerly John Murray), and the holders of the copyright in the text from the Bean and Clarke families.

The site is produced by Arkesis Ltd and designed by Andreja Brulc.
