The book showcases these unique artworks in their different mediums as they are exhibited in the Shirley Sherwood Gallery of Botanical Art. Serving as a guide and keepsake, Petrichor is the perfect takeaway from Collishaw's exciting exhibition. Highlights include the UK premier of Even to the End, a large-scale projected work that immerses viewers in a sequence inspired by the invention of the Wardian Case, The Centrifugal Soul, a zoetrope displaying bird courtship against a backdrop of blooming flowers and The Albion, an eerie spectre of an oak tree suspended between life and death.
