Plant Magic by Gregory J. Kenicer

An informative and entertaining look at why plants have been used in magic and what that tells us about people and plants in a post-magic world. Published by the Royal Botanical Garden Edinburgh.

Plants are magical things. From photosynthesis to folklore they are fundamental to human survival and culture. 

Plant Magic is a reference book for some of the many ways that trees and herbs, ferns, mosses and other organisms such as fungi have been used in magical traditions across Europe and more widely. What is clear from this foray into the supernatural side of botany is that human culture and our uses of plants are both astonishingly diverse and tied together by common ways of explaining the unexplained.
