Ever wondered what coffee in Middle-earth might have tasted like? I was actually thinking about this the other day, and then happened to stumble upon an article about an upcoming book from University of Florida botanist Walter Judd. In Flora of Middle-earth: Plants of JRR Tolkien's Legendarium, from Oxford University Press, Judd answers that burning question in addition to analysing over 160 other plants – either real or based on real species. Each entry features woodcut-style illustrations by Judd himself, very
much in the style of what you might find in a hobbit's book of flowers.
Tolkien was quite fond of nature, as you'll find in reading The Lord of the Rings especially; so it's no wonder there's enough material to devote an entire book to!
