The shop is Santa Maria Novella, founded in the 15th century by Dominican friars and one of the world's oldest pharmacies.
The Piccadilly Arcade
The magical scented item Ahern was enthusing about is not quite so old-school as the shop, but to many of us pot pourri (yes, really!) does have quite the 1990s twang about it: dust-laced decorative bowls of dried up lemons and twigs and mysteriously shaped items purportedly gathered from the forest floor. And always dyed a perplexing burgundy hue. (Looked wonderful with all those lively 1990s wall colours...)
At the Society for the Protection of Unwanted Objects, I quickly locate a tiny brass swan with a hollow body, and some former pavement glass in the shape of a small bowl when turned upside down. That was a fiver as it was chipped and the swan was sitting next to a brass rabbit – no pot pourri function at all but irresistible – so I had to buy that, too. £12.50 the pair.
