A 12-hectare garden
The Botanical Garden is a 12-hectare garden on the slopes of Janiculum, in ancient Corsini villa park, which was the residence of Christina of Sweden. The botanical garden is under the Department of Plant Biology at the University of Rome La Sapienza. The most important collections are Palm, Bosquet of bamboos, valley of ferns, Rose Garden and Japanese Garden. At the top of the hill the original tree structure is preserved, an evergreen Mediterranean forest. This sector is called the Bosco Roman, and through the foliage, between specimens of secular oaks and bananas (350-400 years old) are splendid views over the city.
