Just obtained a new Rock Gardening book.
It is an easy read with lots of photos.
Written by Joseph Tychonievich.
It illustrates the range of how rock gardening might be done.
There is a section on Techniques and propagation.
Then details on about 20 rock garden plant families.
Would be excellent for a beginner rock gardener.
I am not a beginner, but it has inspired me !
