I have several gardening books, I usually pick them up in 2nd shops. I especially like garden design ones and ones specifically for small gardens.
I like the design layouts and the planting schemes.
Given I buy them 2nd hand the books are often old (70s and 80s) and the design aesthetic reflects this.
When I saw a book by designer John Brookes in my library I was pleased to see it was relatively new (2007).
It is very good... the photography is especially inspiring and his design processes very interesting. For example looking for patterns in the surrounding environment.
These are just screaming out to be stitched!
