This is essentially an introductory overview of the whole orchid world, containing history, including the convoluted orchid taxonomy, biology, descriptive essays of selected genera, useful growing advice and, of course, exquisite, large photographs on every page. Take absolutely no notice of the 10-year-old, one star review on Amazon.com, which is a travesty; one is almost tempted to label it malicious.
A problem of finding advice on growing any species/hybrids you happen to have is that there are so many, that no book, or even ten-volume encyclopaedic set, is going to contain them all - leaving aside the fact that taxonomists change names seemingly every week, rendering publications out of date overnight... The best way ahead is to buy your book first, and then buy plants described in the book.
I bought my "very good" used copy from the excellent and reliable "World of Books" on Amazon marketplace for 1p + PP; I regard it as a steal. However many orchid books you have, you won't be sorry you bought this one, and if you are looking for a first, this is as good as any. The fact that it was published 14 years ago is totally irrelevant and detracts not one wit from its value. Nicely written, too, by a prominent figure of the US orchid establishment, and an easy read.
