I saw a lot of Sicilian Snapdragons in Malta, mostly growing in urban areas in rock walls and gardens. The Romans knew about this plant, endemic to Italy and spread it through the empire. Today it is found all through the Mediterranean. The Snapdragons or Dragons, are a contentious issue in the botanical world as genetic studies have caused confusion on which family of plants they belong to. I can see why the Romans liked them and with all the building they did, they were probably quite common in the walls of the empire.
