As Heard on The Daily Gardener Podcast:
Here's a lovely conversational style gardener's dictionary - Garden-pedia: An A-to-Z Guide to Gardening Terms by Pamela Bennett and Maria Zampini.
With more than 200 garden and landscape terms, Garden-pedia is meant to teach, to provide perspectives on terms, and to answer commonly-asked questions. The idea for the book started with Maria Zampini needing to explain basic terms and practices to new hires in the nursery industry and was expanded by Master Gardener Pam Bennett’s experiences with teaching home gardeners.
