Outside the greenhouses, there are tropical and subtropical plants, medicinal and poisonous species, as well as the interesting collection of several ancient and modern roses.

Beyond the central fountain, which houses aquatic plants and is located in the centre of the garden, there are some pools that house both water lilies and other aquatic plants, as well as a pond bordered by Hedera helix ivy and full of Nelumbo nucifera sacred lotus plant. In the same area, a rock formation was specifically built to reproduce the very environment of the Apuan Alps and to host the endemic flora of such environment.

There are about 9.000 plant specimens in the garden. In the meadow of conifers, a Taxodium distichum and a Metasequoia glyptostroboides appear particularly interesting and most definitely worth a visit. Among the oldest plants, there is a Quercus suber cork oak planted in 1805 by the garden director Ottaviano Targioni Tozzetti, and never peeled. There is also a Taxus baccata planted in 1720, and a centuries-old Zelkova serrata.

Inside the garden, specific itineraries have been set up and themed on plant adaptation strategies, and their evolutionary path; there is also a sensory itinerary for visually impaired visitors, that goes across the warm greenhouse and reaches the aromatic species area.

In the warm greenhouse, there is a collection of carnivorous or insectivorous plants that are brought outdoors during the summer. It is made of about 40 species with different methods of feeding: the ascidia looking like pitchers of Nepenthes, the Dionaea beartrap that locks insects among its leaves, and sucking trap typical of the genus Utricola.
