The five volume Trees and Shrubs Hardy in the British Isles by W. J. Bean, usually referred to simply as “Bean”, is a monumental work running to over 4,000 pages. It does what it says: it describes in detail the woody plants (including climbers) that can reasonably be expected to grow outside in Britain (mostly zone 8, some zone 9).

The four A-Z volumes were last revised almost forty years ago, then a supplement appeared in 1988 (see below, click to enlarge), so it does not include recent classification and name changes and recent introductions. Otherwise, it's impressively comprehensive with good descriptions and boundless information on origins and differences between similar plants. It’s invaluable.

Now you can read it - free.

In the first part of a two part initiative, the International Dendrology Society has published the whole thing – all 4,027 pages of it – online. And it’s free: no charge for access. The original four A-Z volumes plus the supplement are currently priced on abebooks.com at £325/$504. Did I mention that the online version is free?

The new online version is easy to navigate and attractively presented. The next step is adding pictures.

You can read more about it on the excellent blog post by John Grimshaw, who’s been heavily involved with the project - and I see he’s had the same idea of including an image of his five volume set as I did!

Take a look at Bean's Trees and Shrubs online - it's invaluable, and it's free.



And what's coming next? Britain's Alpine Garden Society is well into the process of making its invaluable two volume Encyclopaedia Of Alpines available online. It's currently available from abebooks.com for £150/$250.74. You can track the progress of the operation here.
