I got it mainly because I was interested in seeing how much gardening had changed over the years. A lot of its material is still quite useful.
The newest addition to my gardener's bookshelf is a large copy of Steven M. Still's MANUAL OF HERBACEOUS ORNAMENTAL PLANTS. (It runs to a little over 800 pages.) I'm finding lots of useful tidbits of information in it.
[I bought it for a buck at the library sale the first Saturday in April.)
Two very lovely and handy Christmas presents that were given to me this year are:
FOLIAGE by Nancy J. Ondra
THE GOURMET GARDEN by Virginia Hayes
These two books are going to heavily influence my gardening this year since I've decided I absolutely MUST have a kitchen garden this year!
NOTE: This is just four of many...WHAT ARE YOUR FAVORITES???
My oldest gardening book is THE WEEKEND GARDENER by Dorothy H. Jenkins and it dates back to 1950.
