Kew: The Witches Garden is an odd one. It feels more like an exhibition guide printed off and published rather than a book in it's own right. The book flits around through time periods, countries, social class, plants used for good and plants used for evil. In theory it covers a wide array of topics under the plantlore umbrella, but ends up feeling restrictive to just the work of a few renaissance era writers. This is understandable to an extent as the books of these writers have been preserved whereas earlier books or oral herblore traditions will have been lost to time, but it makes the quick non-European, or non-British specifically, lines feel more like underdeveloped asides.
A lot of the information also feels surface level or not particularly well proofread. Various plants or concepts are listed without explanation or example, and some terms (such as a vascular plants) are mentioned in one chapter but only defined in a later chapter. We get more in depth information at the end of each chapter where we have a page or two dedicated to talking about one specific plant, completing the exhibition like feel, where the beginning of the chapter is the information board at the start of that room and then the individual plant pages are a display case contents. Unfortunately a lot of that plant information starts to become very repetitive, there are only so many times you can read about how white flowers brought into the home are bad luck, or how almost any plant can be used by a girl to predict when she will get married. It's also a shame that there is barely any mention as whether, or if they do how, any of these treatments actually work, though unnecessary in the case of the husband predications!
There are some sections which get a bit more interesting. The one on Nicholas Culpeper is a standout, covering how social upheaval at the time affected medical treatment, as Culpepper railed against the College of Physicians to give medical information and affordable treatment to regular people. These social aspects are easily the most interesting, such as how the traditional role of women healers was restricted by male dominated medical establishment. Unfortunately, this is a minority of the book, but these more chronological sections show how a more engaging book could perhaps have been written.
Aesthetically the book is very pretty. As a coffee table book to glance into, or for looking up information on a particular plant, it works well. The book doesn't skimp on the illustrations and colour, with each page spread having one page dedicated to a large single image, with the other page often having smaller illustrations. It does cut down on the amount of information you get to in the 201 pages (again adding to the exhibition like feel), though given how repetitive the book was maybe that's a blessing.
