Could you please recommend a book treating about spotted, marginated and
other variegated plants? I have seen Houtman's "Variegated Trees and Shrubs"
and it seemed interesting, but perhaps there are other (better) books? And
something about gardening under very dry conditions, please, I have likewise
found Beth Chatto's book on dry gravel garden, any others worth buying and
reading?

One book well worth looking at is :
An Illustrated guide to Flowering Trees and Shrubs
Edited by Cyril C.Harris Pub. Little,Brown & Co. 1999
ISBN 0-316-84761--5 148pps. Softback
