Flora
The Colosseum has a wide and well-documented history of flora ever since Domenico Panaroli made the first catalogue of its plants in 1643. Since then, 684 species have been identified there. The peak was in 1855 (420 species). Attempts were made in 1871 to eradicate the vegetation, because of concerns over the damage that was being caused to the masonry, but much of it has returned. 242 species have been counted today and of the species first identified by Panaroli, 200 remain.
The variation of plants can be explained by the change of climate in Rome through the centuries. Additionally, bird migration, flower blooming, and the growth of Rome that caused the Colosseum to become embedded within the modern city centre rather than on the outskirts of the ancient city, as well as deliberate transport of species, are also contributing causes. One other romantic reason often given is their seeds being unwittingly transported on the animals brought there from all corners of the empire.
