“The Treadwell’s Book of Plant Magic is my go-to guide for all things botanically magical. Christina Oakley Harrington has written a marvel of a volume sure to arm any witch—or anyone—with the knowledge they need to infuse their lives with plant enchantments of all sorts. This is the wise and wondrous herbal reference book we have been waiting for!” —Pam Grossman, author of Waking the Witch: Reflections on Women, Magic, and Power
