Chaenorhinum origanifolium (also known as Linaria origanifolia) is native to mountainous regions of the Iberian Peninsula and the Balearic Islands but you will see it in abundance around the Abbey, especially growing in cracks in the stonework. We are told that this is the only place where it grows wild in this country so it can be considered a great rarity (although you can now purchase it in garden centres!). It was also once found at Wells Cathedral but cleaning and repointing removed its habitat. One explanation for its presence here is that it could have been brought by a visiting Spanish nun in the Middle Ages.
