I created my first personalised perfume in 1977 for my bride to wear on our wedding day. It was a white powdery floral fragrance based on the iris root. Since then, iris has been one of my obsessions. It is the most unclassifiable, elegant, beautiful, expensive ingredient. The root must be dried for three years before its precious essence can be extracted. But it does not last as much as it costs and making it last is almost… impossible!
