Why we do what we do

This plant really likes a stony environment. In our area, that means that they are bound to the city, because that is where to find stony surfaces. Originally, this plant comes from around the Mediterranean, but is has slowly moved north. Since the 17th century, this plant has been a resident of our villages and towns. Initially only along the coast, but in the course of time this plant moved further and further inland, via roads, building sites, and railway embankments. Now, it has also discovered a prime location on the old city walls of Maastricht.
