Book excerpt: More than anything else, colour is how people instinctively think about flowers — whether planning for a wedding, commemorating an occasion, or looking for an easy way to bring life into a space. With 400 gorgeously photographed cut flowers organized to span the full spectrum of shades, Flower Colour Guide is the essential tool for flower selection and arrangement, and a primer to understanding and appreciating flowers and colour. 'This is the book we wish we had to help us before we started,' say authors Darroch and Michael Putnam, the duo behind New York's leading floral design studio, Putnam & Putnam.
