'In his summary he contends that 'flowers have been so instrumental forming human ideas of paradise.' His notions are supported by a broad range of illustrations that celebrate the great beauty of flowers in a variety of forms.'

'At over 400 pages, this is a long work, but it is full of superb illustrations, providing instant appeal... it is also a book of substance as far as the writing is concerned... I consider this to be a book which will 'grow' on the reader - to extend the flower analogy - and it is full of memorable quotes, which the mathematically challenged reader (like me), or the newcomer to the perennial philosophy, can hold on to while waiting for full understanding to emerge.

'I've been looking at plants all my life and it's one of my great pleasures, Keith Critchlow's book adds new dimensions to this enjoyment and shows how number and geometry are made manifest in the forms that we see in every garden, in wild flowers and in the cut flowers that decorate our rooms... The plentiful illustrations help make this a book of inspiration and insight.'
- Dr Rupert Sheldrake
'... a delightful and instructive companion... It is a fascinating book, full of things useful and pleasing to know. And I admire the honest circularity of its plot that begins in mystery, passes through much knowledge, and returns again to mystery.'

'I have been waiting thirty-five years for this book.'
- Julian Barnard, author of Bach Flower Remedies: Form and Function
'Like many people, I've been eagerly awaiting the publication of this book, and I have to say that it has been a real delight finally to read its inspirational thoughts and also to contemplate the large number of beautiful images and geometrical diagrams that is contains ... The Hidden Geometry of Flowers is a wonderful gift to the growing number of people who, dissatisfied with the impoverished and disenchanted worldview of materialistic science, are seeking to relate to the spiritual in nature once again. It is also a major contribution to the holistic science of the plant world, complementing studies by Goethean and anthroposophically inspired researchers into the formative forces at work in the plant kingdom... Anyone who gives proper attention to [this book] will feel that they are indeed brought closer to the mysterious form-creating life-processes that emanate from the world of spirit, and for this reason it is an enormously valuable contribution to all who are endeavouring to work towards a more holistic and spiritual awareness of the plant world.'

'Keith Critchlow has created a masterpiece, which speaks not only through his inspired and informative text, but also through 560 color [sic] illustrations combining his superb flower photography with hand-drawn geometric patterns. The result is a celebration of the geometric lawfulness of flower forms that embody universal spiritual archetypes... The Hidden Geometry of Flowers is absolutely a must-read book.'
- Flower Essence Society
'This book is a definitive work on the geometry of the relationship between Nature and the Cosmos... Professor Critchlow's masterpiece is the product of a lifelong labour of love and observation, illustrated with many of his personal drawings... As well as being informative and eye-opening, reading this book is refreshing, like a visit to paradise.
'In his elegantly presented large-format book, Prof. Keith Critchlow includes over 500 breathtaking colour photographs, illustrations and hand drawings to go with his engaging text ... Beauty really is truth, as this magnificent work shows.'
'This remarkable and beautiful book is the culmination of years of research into the nature and geometry of flowers, drawing on the author's extensive understanding of Platonic philosophy as a means of expressing and understanding the Good, the Beautiful and the True... Reading the book is a form of living education which means that you will never respond to (I did not say look at) flowers in quite the same way again.'

'This book reads like the unfurling of a lifetime's observation, and afterwards you look at the whole world differently, not just the garden.'
- Garden Design Journal
'I eagerly awaited the publication of this book, and I have to say that it was a real delight finally to read its inspirational thoughts and also to contemplate the large number of beautiful images and geometrical diagrams it contains... [The book's] analyses open one's eyes to the extraordinary ability of flowers to harness and express geometrical forms and proportions... a wonderful gift to the growing number of people who... are seeking to relate to the spiritual in nature once again. It is also a major contribution to the holisitic science of the plant world... [it] is an enormously valuable contribution to all who are endeavouring to work towards a more holistic and spiritual awareness of the plant world.'
