In my travels, I happened upon quince in Dublin and quince in Rome. The first photo is of the Dublin quince, times three. The other three photos are of the Rome quince, which were much larger and more familiar in shape to the variety that I’ve seen here in Oakland.
Rome was bursting at the seams with public and backyard citrus trees, much like Sevilla is bursting with the bitter orange so named in its honor. In Rome, here is a list of backyard fruit that I was able to chart: pommegranates, persimmons, olives, lemon verbena, bay leaves, citrus galore, quince, wild nettles.
